* Attached is a makefile I hacked up to build pg_config under MSVC - theBruce Momjian2005-06-14
| | | | | | | reason is that it's required (more or less) in order to build the latest DBD::Pg code and I was testing that out under MSVC. Andrew Dunstan
* Add GUC krb_server_hostname so the server hostname can be specified asBruce Momjian2005-06-14
| | | | | | | | | part of service principal. If not set, any service principal matching an entry in the keytab can be used. NEW KERBEROS MATCHING BEHAVIOR FOR 8.1. Todd Kover
* The random selection in function linear() could deliver a value equal to maxTom Lane2005-06-14
| | | | | | | if geqo_rand() returns exactly 1.0, resulting in failure due to indexing off the end of the pool array. Also, since this is using inexact float math, it seems wise to guard against roundoff error producing values slightly outside the expected range. Per report from bug@zedware.org.
* WAL for GiST. It work for online backup and so on, but onTeodor Sigaev2005-06-14
| | | | | | | recovery after crash (power loss etc) it may say that it can't restore index and index should be reindexed. Some refactoring code.
* Allow the parameters to PL/PgSQL's RAISE statement to be expressions,Neil Conway2005-06-14
| | | | | | | | instead of just scalar variables. Add regression tests and update the documentation. Along the way, remove some redundant error checking code from exec_stmt_perform(). Original patch from Pavel Stehule, reworked by Neil Conway.
* Teach planner to optionally ignore index columns that have an equalityTom Lane2005-06-14
| | | | | | | | | constraint while determining whether the index sort order matches the query's ORDER BY. This for example allows an index on (x,y) to match ... WHERE x = 42 ORDER BY y; It only works for btree indexes, but since those are the only ones we currently have that are ordered at all, that's good enough for now. Per popular demand.
* Add -L option to psql to log sessions.Bruce Momjian2005-06-14

* Cleanup for "#option dump" in PL/PgSQL: don't print empty ELSE blocks,Neil Conway2005-06-14
| | | | | fix two grammatical errors, and print the INTO target of EXECUTE INTO if one is specified.
* Change the planner to allow indexscan qualification clauses to useTom Lane2005-06-13
| | | | | | | | | nonconsecutive columns of a multicolumn index, as per discussion around mid-May (pghackers thread "Best way to scan on-disk bitmaps"). This turns out to require only minimal changes in btree, and so far as I can see none at all in GiST. btcostestimate did need some work, but its original assumption that index selectivity == heap selectivity was quite bogus even before this.
* Per discussion on -hackers, this patch changes psql's "expanded" outputNeil Conway2005-06-13
| | | | | | mode to only affect the presentation of normal query results, not the output of psql slash commands. Documentation updated. I also made some unrelated minor psql cleanup. Per suggestion from Stuart Cooper.
* Adjust lo_open() so that specifying INV_READ without INV_WRITE createsTom Lane2005-06-13
| | | | | | | | | | a descriptor that uses the current transaction snapshot, rather than SnapshotNow as it did before (and still does if INV_WRITE is set). This means pg_dump will now dump a consistent snapshot of large object contents, as it never could do before. Also, add a lo_create() function that is similar to lo_creat() but allows the desired OID of the large object to be specified. This will simplify pg_restore considerably (but I'll fix that in a separate commit).
* This patch removes some old code from libpq that implements a URI-likeNeil Conway2005-06-12
| | | | | | syntax for database connection parameters. It has been inside an #ifdef NOT_USED block since 2001 or so and is marked as "broken", so I don't think it is likely to be rehabilitated any time soon.
* libpq was not consistently checking for memory allocation failures. ThisNeil Conway2005-06-12
| | | | | | | patch adds missing checks to the call sites of malloc(), strdup(), PQmakeEmptyPGresult(), pqResultAlloc(), and pqResultStrdup(), and updates the documentation. Per original report from Volkan Yazici about PQmakeEmptyPGresult() not checking for malloc() failure.
* Separate predicate-testing code out of indxpath.c, making it a moduleTom Lane2005-06-10
| | | | | in its own right. As proposed by Simon Riggs, but with some editorializing of my own.
* Adjust comment about %t and %s to cover %m as well. Some trivialTom Lane2005-06-10

* Implement two new special variables in PL/PgSQL: SQLSTATE and SQLERRM.Neil Conway2005-06-10
| | | | | | | | | | | | | | These contain the SQLSTATE and error message of the current exception, respectively. They are scope-local variables that are only defined in exception handlers (so attempting to reference them outside an exception handler is an error). Update the regression tests and the documentation. Also, do some minor related cleanup: export an unpack_sql_state() function from the backend and use it to unpack a SQLSTATE into a string, and add a free_var() function to pl_exec.c Original patch from Pavel Stehule, review by Neil Conway.
* Use saveHistory so we get a nice error message on failure.Bruce Momjian2005-06-10

* the following patch makes the filename used to store the readlineBruce Momjian2005-06-10
| | | | | | | | | | | | | | history customizable through a variable named HISTFILE, analogous to psql's already implemented HISTCONTROL and HISTSIZE variables, and bash's HISTFILE-Variable. The motivation was to be able to get psql to maintain separate histories for separate databases. This is now easily achievable through a line like the following in ~/.psqlrc: \set HISTFILE ~/.psql_history-:DBNAME Andreas Seltenreich

* Quick hack to allow the outer query's tuple_fraction to be passed downTom Lane2005-06-10
| | | | | | | | | | | to a subquery if the outer query is simple enough that the LIMIT can be reflected directly to the subquery. This didn't use to be very interesting, because a subquery that couldn't have been flattened into the upper query was usually not going to be very responsive to tuple_fraction anyway. But with new code that allows UNION ALL subqueries to pay attention to tuple_fraction, this is useful to do. In particular this lets the optimization occur when the UNION ALL is directly inside a view.
* Add the "PGPASSFILE" environment variable to specify to the passwordBruce Momjian2005-06-10
| | | | | | file. Andrew Dunstan
* If a LIMIT is applied to a UNION ALL query, plan each UNION arm asTom Lane2005-06-10
| | | | | | | if the limit were directly applied to it. This does not actually add a LIMIT plan node to the generated subqueries --- that would be useless overhead --- but it does cause the planner to prefer fast- start plans when the limit is small. After an idea from Phil Endecott.
* Revise searching of subplan target lists to use something more efficientTom Lane2005-06-10
| | | | | than tlist_member calls. Building a large join tlist is still O(N^2), but with a much smaller constant factor than before.
* This patch shows the full path name when doing a \s in psql,Bruce Momjian2005-06-09
| | | | | | if you have previously issued a \cd command. Greg Sabino Mullane

* Restructure log_line_prefix options to be clearer:Bruce Momjian2005-06-09
| | | | | | | | | | | | | | | | | | #log_line_prefix = '' # %u = user name # %d = database name # %r = remote host and port # %h = remote host # %p = PID # %t = timestamp # %m = timestamp with milliseconds # %i = command tag # %c = session id # %l = session line number # %s = session start timestamp # %x = transaction id # %q = stop here in non-session processes # %% = '%' # e.g. '<%u%%%d> '
* This patch against 8.0.0beta1 source adds log_line_prefix options forBruce Momjian2005-06-09
| | | | | | | millisecond timestamps (%m) and remote host (%h). The milliseconds are useful for QPS measurements. Ed L.
* Fix typo in comment, per Alvaro.Tom Lane2005-06-09

* Fix assign_datestyle() so that it doesn't misleadingly complain aboutTom Lane2005-06-09
| | | | | 'conflicting datestyle specifications' for input that's actually only redundant, such as SET DATESTYLE = MDY, MDY. Per recent gripe.
* Make SPI set SPI_processed for CREATE TABLE AS / SELECT INTO commands;Tom Lane2005-06-09
| | | | | | this in turn causes CREATE TABLE AS in plpgsql to set ROW_COUNT. This is how it behaved before 7.4; I had unintentionally changed the behavior in a bit of sloppy micro-optimization.

* Put a critical section around update of hash index metapage. PerTom Lane2005-06-09

* Since I needed this feature badly, I added the -n / --schema switch toBruce Momjian2005-06-09
| | | | | | | | pg_restore. It restores the given schemaname only. It can be used in conjunction with the -t and other switches to make the selection very fine grained. Richard van den Bergg, CISSP
* Please find attached a patch (diff -c against cvs HEAD) to add aBruce Momjian2005-06-09

* I've created a patch which adds support for troff "-ms" output toBruce Momjian2005-06-09
| | | | | | | | | | | | | | | | | | | | | | | psql. i.e. "\pset format troff-ms". The patch also corrects some problems with the "latex" format, notably defining an extra column in the output table, and correcting some alignment issues; it also changes the output to match the border setting as documented in the manual page and as shown with the "aligned" format. The troff-ms output is mostly identical to the latex output allowing for the differences between the two typesetters. The output should be saved in a file and piped as follows: cat file | tbl | troff -T ps -ms > file.ps or tbl file | troff -T ps -ms > file.ps Because it contains tabs, you'll need to redirect psql output or use "script", rather than pasting from a terminal window, due to the tabs which can be replaced with spaces.

* Simplify the planner's join clause management by storing join clausesTom Lane2005-06-09
| | | | | | | | | | of a relation in a flat 'joininfo' list. The former arrangement grouped the join clauses according to the set of unjoined relids used in each; however, profiling on test cases involving lots of joins proves that that data structure is a net loss. It takes more time to group the join clauses together than is saved by avoiding duplicate tests later. It doesn't help any that there are usually not more than one or two clauses per group ...
* Marginal hack to avoid spending a lot of time in find_join_rel duringTom Lane2005-06-08
| | | | | large planning problems: when the list of join rels gets too long, make an auxiliary hash table that hashes on the identifying Bitmapset.
* Remove grammar productions for prefix and postfix % and ^ operators,Tom Lane2005-06-08
| | | | | | | | | | as well as the existing pg_catalog entries for prefix and postfix %. These have never been documented, though they did appear in one old regression test. This avoids surprising behavior in cases like "SELECT -25 % -10". Per recent discussion. Note: although there is a catalog change here, I did not force initdb since there's no harm in leaving the inaccessible entries in one's copy of pg_operator.
* Change WAL-logging scheme for multixacts to be more like regularTom Lane2005-06-08
| | | | | | transaction IDs, rather than like subtrans; in particular, the information now survives a database restart. Per previous discussion, this is essential for PITR log shipping and for 2PC.
* Correct an omission in the syntax error message emitted by EXECUTE INTONeil Conway2005-06-08
| | | | in pl/pgsql.
* Mention ipcrm and ipcclean in error message.Bruce Momjian2005-06-07
|
* Use just NULL not NULL::TEXT --- the latter coding is unnecessary andTom Lane2005-06-07
| | | | not schema-safe. Per report from Jochem van Dieten.
* Add a function lastval(), which returns the value returned by theNeil Conway2005-06-07
| | | | | | last nextval() or setval() performed by the current session. Update the docs, add regression tests, and bump the catalog version. Patch from Dennis Björklund, various improvements by Neil Conway.
