* Make the enumvals column of pg_settings be text[] instead of justMagnus Hagander2008-11-21
| | | | a comma separated string.
* Use relation_expr for TABLE command, requested by Tom.Peter Eisentraut2008-11-21

* Issue a proper error message when MD5 is attempted whenBruce Momjian2008-11-20
| | | | | | db_user_namespace is enabled. Also document this limitation.
* Fix breakage of bitmap scan plan creation for special index operators suchTom Lane2008-11-20
| | | | | | | | as LIKE. I oversimplified this code when removing support for plan-time determination of index operator lossiness back in April --- I had thought create_bitmap_subplan could stop returning two separate lists of qual conditions, but it still must so that we can treat special operators correctly in create_bitmap_scan_plan. Per report from Rushabh Lathia.

* Add support for using SSL client certificates to authenticate to theMagnus Hagander2008-11-20
| | | | database (only for SSL connections, obviously).
* Control client certificate requesting with the pg_hba option "clientcert"Magnus Hagander2008-11-20
| | | | instead of just relying on the root certificate file to be present.
* Rethink the way FSM truncation works. Instead of WAL-logging FSMHeikki Linnakangas2008-11-19
| | | | | | | | | | | | | | | truncations in FSM code, call FreeSpaceMapTruncateRel from smgr_redo. To make that cleaner from modularity point of view, move the WAL-logging one level up to RelationTruncate, and move RelationTruncate and all the related WAL-logging to new src/backend/catalog/storage.c file. Introduce new RelationCreateStorage and RelationDropStorage functions that are used instead of calling smgrcreate/smgrscheduleunlink directly. Move the pending rel deletion stuff from smgrcreate/smgrscheduleunlink to the new functions. This leaves smgr.c as a thin wrapper around md.c; all the transactional stuff is now in storage.c. This will make it easier to add new forks with similar truncation logic, like the visibility map.
* Fix compiler warning "res may be used uninitialized in this function".Teodor Sigaev2008-11-19
| | | | | Actually, it can't but some compilers are not smart enough. Per Peter Eisentraut gripe.
* Fix define_custom_variable so that SUSET custom variables behaveTom Lane2008-11-19
| | | | | somewhat reasonably. It's not perfect, but it beats the kluge proposed in the auto-explain patch ...
* Some infrastructure changes for the upcoming auto-explain contrib module:Tom Lane2008-11-19
| | | | | | | | | | | | | | | | | | | | | | * Refactor explain.c slightly to export a convenient-to-use subroutine for printing EXPLAIN results. * Provide hooks for plugins to get control at ExecutorStart and ExecutorEnd as well as ExecutorRun. * Add some minimal support for tracking the total runtime of ExecutorRun. This code won't actually do anything unless a plugin prods it to. * Change the API of the DefineCustomXXXVariable functions to allow nonzero "flags" to be specified for a custom GUC variable. While at it, also make the "bootstrap" default value for custom GUCs be explicitly specified as a parameter to these functions. This is to eliminate confusion over where the default comes from, as has been expressed in the past by some users of the custom-variable facility. * Refactor GUC code a bit to ensure that a custom variable gets initialized to something valid (like its default value) even if the placeholder value was invalid.
* Ident authentication over Unix-domain sockets on Solaris, usingPeter Eisentraut2008-11-18
| | | | | | getpeerucred() function. Author: Garick Hamlin <ghamlin@isc.upenn.edu>
* Replace plain-memory ordered array by binary tree in ts_stat() function.Teodor Sigaev2008-11-17
| | | | Performance is increased from 50% up to 10^3 times depending on data.
* Modify UPDATE/DELETE WHERE CURRENT OF to use the FOR UPDATE infrastructure toTom Lane2008-11-16
| | | | | | | locate the target row, if the cursor was declared with FOR UPDATE or FOR SHARE. This approach is more flexible and reliable than digging through the plan tree; for instance it can cope with join cursors. But we still provide the old code for use with non-FOR-UPDATE cursors. Per gripe from Robert Haas.
* Fix crash of xmlconcat(NULL)Peter Eisentraut2008-11-15
| | | | also backpatched to 8.3
* Make SELECT FOR UPDATE/SHARE work on inheritance trees, by having the planTom Lane2008-11-15
| | | | | | | | | return the tableoid as well as the ctid for any FOR UPDATE targets that have child tables. All child tables are listed in the ExecRowMark list, but the executor just skips the ones that didn't produce the current row. Curiously, this longstanding restriction doesn't seem to have been documented anywhere; so no doc changes.
* In CREATE AGGREGATE, allow the transition datatype to be "internal", but onlyTom Lane2008-11-14
| | | | | | | | | if the user is superuser. This makes available to extension modules the same sort of trick being practiced by array_agg(). The reason for the superuser restriction is that you could crash the system by connecting up an incompatible pair of internal-using functions as an aggregate. It shouldn't interfere with any legitimate use, since you'd have to be superuser to create the internal-using transition and final functions anyway.
* Make CREATE CONVERSION verify that a putative encoding conversion functionTom Lane2008-11-14
| | | | | | returns VOID. This is the last of the easy fixes I recommended in 11870.1218838360@sss.pgh.pa.us --- the others got done awhile ago but I forgot about this one.
* Fix oversight in previous error-reporting patch; mustn't pfree path stringHeikki Linnakangas2008-11-14
| | | | before passing it to elog.
* Actually, instead of whining about how type internal might not safely storeTom Lane2008-11-14
| | | | | a pointer, why don't we just fix that. Every known use of "internal" really means a pointer anyway.
* Replace the usage of heap_addheader to create pg_attribute tuples with regularAlvaro Herrera2008-11-14
| | | | | | | | heap_form_tuple. Since this removes the last remaining caller of heap_addheader, remove it. Extracted from the column privileges patch from Stephen Frost, with further code cleanups by me.
* Implement the basic form of UNNEST, ie unnest(anyarray) returns setofTom Lane2008-11-14
| | | | | | | anyelement. This lacks the WITH ORDINALITY option, as well as the multiple input arrays option added in the most recent SQL specs. But it's still a pretty useful subset of the spec's functionality, and it is enough to allow obsoleting contrib/intagg.
* Minor code clarity improvements in array_agg functions, and add a commentTom Lane2008-11-14
| | | | about how this is playing fast and loose with the type system.
* Prevent synchronous scan during GIN index build, because GIN is optimizedTom Lane2008-11-13
| | | | | | | | | for inserting tuples in increasing TID order. It's not clear whether this fully explains Ivan Sergio Borgonovo's complaint, but simple testing confirms that a scan that doesn't start at block 0 can slow GIN build by a factor of three or four. Backpatch to 8.3. Sync scan didn't exist before that.
* array_agg aggregate function, as per SQL:2008, but without ORDER BY clausePeter Eisentraut2008-11-13
| | | | | | | Rearrange the documentation a bit now that array_agg and xmlagg have similar semantics and issues. best of Robert Haas, Jeff Davis, Peter Eisentraut
* Removed two non-terminals:Michael Meskes2008-11-13
| | | | | - FloatOnly: only used by NumericOnly, instead put the FloatOnly production into NumericOnly - IntegerOnly: only used by NumericOnly and one ALTER TABLE rule, replacement SignedIconst is already used in several other places
* Arrange to cache the results of looking up a btree predicate proof comparisonTom Lane2008-11-13
| | | | | | | | | | | operator. The result depends only on the two input operators and the proof direction (imply or refute), so it's easy to cache. This provides a very large savings in cases such as Sergey Konoplev's long NOT-IN-list example, where predtest spends all its time repeatedly figuring out that the same pair of operators cannot be used to prove anything. (But of course the O(N^2) behavior still catches up with you eventually.) I'm not convinced it buys a whole lot when constraint_exclusion isn't turned on, but it's not a lot of added code so we might as well cache all the time.
* In predtest.c, install a limit on the number of branches we will process inTom Lane2008-11-12
| | | | | | | | | | | | | | | | | AND, OR, or equivalent clauses: if there are too many (more than 100) just exit without proving anything. This ensures that we don't spend O(N^2) time trying (and most likely failing) to prove anything about very long IN lists and similar cases. Also, install a couple of CHECK_FOR_INTERRUPTS calls to ensure that a long proof attempt can be interrupted. Per gripe from Sergey Konoplev. Back-patch the whole patch to 8.2 and just the CHECK_FOR_INTERRUPTS addition to 8.1. (The rest of the patch doesn't apply cleanly, and since 8.1 doesn't show the complained-of behavior anyway, it doesn't seem necessary to work hard on it.)
* Do not use ICONST/SCONST in rules other than Iconst/Sconst.Michael Meskes2008-11-12
|
* array_length() function, and for SQL compatibility also cardinality()Peter Eisentraut2008-11-12
| | | | | | | | | | function as a special case. This version still has the suspicious behavior of returning null for an empty array (rather than zero), but this may need a wholesale revision of empty array behavior, currently under discussion. Jim Nasby, Robert Haas, Peter Eisentraut
* Fix off-by-one error in autovacuum shmem struct sizing. This could lead toHeikki Linnakangas2008-11-12
| | | | | | | autovacuum worker sending SIGUSR1 signal to wrong process, per Zou Yong's report. Backpatch to 8.3.
* Clean up the ancient decision to show only two fractional-seconds digitsTom Lane2008-11-12
| | | | | | | | | | | | | in "postgres_verbose" intervalstyle, and the equally arbitrary decision to show at least two fractional-seconds digits in most other datetime display styles. This results in some minor changes in the expected regression test outputs. Also, coalesce a lot of repetitive code in datetime.c into subroutines, for clarity and ease of maintenance. In particular this roughly halves the number of #ifdef HAVE_INT64_TIMESTAMP segments. Ron Mayer, with some additional kibitzing from Tom Lane
* Ensure that the phrels sets of PlaceHolderVars appearing in an AppendRelInfo'sTom Lane2008-11-11
| | | | | | | translated_vars list get updated when pulling up an appendrel member. It's not clear that this really matters at present, since relatively little gets done with the outputs of an appendrel child relation; but it probably will come back to bite us sometime if we leave them with the wrong values.
* Get rid of adjust_appendrel_attr_needed(), which has been broken ever sinceTom Lane2008-11-11
| | | | | | | | | | | we extended the appendrel mechanism to support UNION ALL optimization. The reason nobody noticed was that we are not actually using attr_needed data for appendrel children; hence it seems more reasonable to rip it out than fix it. Back-patch to 8.2 because an Assert failure is possible in corner cases. Per examination of an example from Jim Nasby. In HEAD, also get rid of AppendRelInfo.col_mappings, which is quite inadequate to represent UNION ALL situations; depend entirely on translated_vars instead.
* Fix sloppy omission of now-required #include's.Tom Lane2008-11-11
|
* Change error messages to print the physical path, likeHeikki Linnakangas2008-11-11
| | | | | | "base/11517/3767_fsm", instead of symbolic names like "1663/11517/3767/1", per Alvaro's suggestion. I didn't change the messages in the higher-level index, heap and FSM routines, though, where the fork is implicit.
* Add an explicit caution about how to use pg_do_encoding_conversion withTom Lane2008-11-11
| | | | non-null-terminated input. Per discussion with ITAGAKI Takahiro.
* Add support for input and output of interval values formatted per ISO 8601;Tom Lane2008-11-11
| | | | | | | | specifically, we can input either the "format with designators" or the "alternative format", and we can output the former when IntervalStyle is set to iso_8601. Ron Mayer
* Fix a case of string building.Alvaro Herrera2008-11-10
|
* Fix bugs in sqlchar_to_unicode and unicode_to_sqlchar: both were measuringTom Lane2008-11-10
| | | | | | the length of a UTF8 character with pg_mblen (wrong if DB encoding isn't UTF8), and the latter was blithely assuming that a static buffer would somehow revert to all zeroes for each use.
* Fix 'Q' format char parsing in the new to_timestamp() code. Used to crash.Heikki Linnakangas2008-11-10
|
* pg_do_encoding_conversion cannot return NULL (at least not unless the inputTom Lane2008-11-10
| | | | is NULL), so remove some useless tests for the case.
* Make relhasrules and relhastriggers work like relhasindex, namely we letTom Lane2008-11-10
| | | | VACUUM reset them to false rather than trying to clean 'em up during DROP.
* Replace pg_class.reltriggers with relhastriggers, which is just a boolean hintTom Lane2008-11-09
| | | | | | | | | | | | | ("there might be triggers") rather than an exact count. This is necessary catalog infrastructure for the upcoming patch to reduce the strength of locking needed for trigger addition/removal. Split out and committed separately for ease of reviewing/testing. In passing, also get rid of the unused pg_class columns relukeys, relfkeys, and relrefs, which haven't been maintained in many years and now have no chance of ever being maintained (because of wishing to avoid locking). Simon Riggs
* Add a startup check that pg_xlog and pg_xlog/archive_status exist.Tom Lane2008-11-09
| | | | | | | If the latter doesn't exist, automatically recreate it. (We don't do this for pg_xlog, though, per discussion.) Jonah Harris
* Add a new GUC variable called "IntervalStyle" that decouples interval outputTom Lane2008-11-09
| | | | | | | | | | from DateStyle, and create a new interval style that produces output matching the SQL standard (at least for interval values that fall within the standard's restrictions). IntervalStyle is also used to resolve the conflict between the standard and traditional Postgres rules for interpreting negative interval input. Ron Mayer
* Fix recently added code for SQL years-months interval syntax so thatTom Lane2008-11-08
| | | | | it behaves correctly for a leading minus sign, zero year value, and nonzero month value. Per discussion with Ron Mayer.
* Implement ALTER DATABASE SET TABLESPACE to move a whole database (or at leastTom Lane2008-11-07
| | | | | | as much of it as lives in its default tablespace) to a new tablespace. Guillaume Lelarge, with some help from Bernd Helmle and Tom Lane
* Improve bulk-insert performance by keeping the current target buffer pinnedTom Lane2008-11-06
| | | | | | | (but not locked, as that would risk deadlocks). Also, make it work in a small ring of buffers to avoid having bulk inserts trash the whole buffer arena. Robert Haas, after an idea of Simon Riggs'.
* The logic in systable_beginscan to translate heap attribute numbers toHeikki Linnakangas2008-11-06
| | | | | index column numbers needs to handle the case where you have more than one scankey on the same index column. toast_fetch_datum_slice() needs it.
