* - Check for NULL before checking whether argument is an array.Michael Meskes2005-08-24
| | | | | - Remove stary character from string quoting. - Fixed check to report missing varchar pointer implementation.
* Add ALTER TABLE ENABLE/DISABLE TRIGGER commands. Change pg_dump toTom Lane2005-08-23
| | | | | | use these instead of its previous hack of changing pg_class.reltriggers. Documentation is lacking, will add that later. Patch by Satoshi Nagayasu, review and some extra work by Tom Lane.
* Add new file for win32 threading.Bruce Momjian2005-08-23

* The attached patch updates the thread test program to run stand-alone onBruce Momjian2005-08-23
| | | | | | | | Windows. The test itself is bypassed in configure as discussed, and libpq has been updated appropriately to allow it to build in thread-safe mode. Dave Page
* Clean up some very old and crufty code for TID scan planning. Not muchTom Lane2005-08-23
| | | | | functional difference really, but make use of stuff added to the planner since this code was touched last.
* Back out incorrect commit.Bruce Momjian2005-08-23
|
* Fix function name.Bruce Momjian2005-08-23
|
* Fix broken lrand48() implementation, per Merlin Moncure.Tom Lane2005-08-23
|
* Fix wrong dependency on owner created by ALTER OPCLASS OWNER.Tom Lane2005-08-23
| | | | Per Alvaro.
* Rewrite gather-write patch into something less obviously bolted onTom Lane2005-08-22
| | | | | | | | | after the fact. Fix bug with incorrect test for whether we are at end of logfile segment. Arrange for writes triggered by XLogInsert's is-cache-more-than-half-full test to synchronize with the cache boundaries, so that in long transactions we tend to write alternating halves of the cache rather than randomly chosen portions of it; this saves one more write syscall per cache load.
* Back out incorrect use of E'' escape addition.Bruce Momjian2005-08-22
|
* Cause ALTER INDEX OWNER to generate a warning and do nothing, rather thanTom Lane2005-08-22
| | | | | | | erroring out as it has done for the last couple weeks. Document that this form is now ignored because indexes can't usefully have different owners from their parent tables. Fix pg_dump to not generate ALTER OWNER commands for indexes.
* Fix unwanted denial of ALTER OWNER rights to superusers. There was someTom Lane2005-08-22
| | | | | | discussion of getting around this by relaxing the checks made for regular users, but I'm disinclined to toy with the security model right now, so just special-case it for superusers where needed.
* enable_constraint_exclusion => constraint_exclusionBruce Momjian2005-08-22
| | | | Also improve wording.
* Improve xid wraparound message (the server isn't really shut down, justBruce Momjian2005-08-22
| | | | | | | | | not accepting queries). errmsg("database is not accepting queries to avoid wraparound data loss in database \"%s\"", errhint("Stop the postmaster and use a standalone backend to VACUUM database \"%s\".",
* Use an initdb-time test to see if the local version of getaddrinfo()Tom Lane2005-08-22
| | | | | chokes on IPv6 addresses, and comment out the IPv6 entry in the default pg_hba.conf if so. Per Andrew Dunstan.
* Fix some inconsistent choices of datatypes in xlog.c. Make bufferTom Lane2005-08-22
| | | | | indexes all be int, rather than variously int, uint16 and uint32; add some casts where necessary to support large buffer arrays.
* Minor GUC cleanups: document krb_server_hostname and custom_variable_classesTom Lane2005-08-21
| | | | | | in postgresql.conf.sample, mark custom_variable_classes as SIGHUP not POSTMASTER to agree with the documentation (I can't see a reason it has to be POSTMASTER so I think the docs are right).
* Seems that the childXids list would be better based on Oid lists thanTom Lane2005-08-20
| | | | integer lists.
* Convert the arithmetic for shared memory size calculation from 'int'Tom Lane2005-08-20
| | | | | | | | | | | to 'Size' (that is, size_t), and install overflow detection checks in it. This allows us to remove the former arbitrary restrictions on NBuffers etc. It won't make any difference in a 32-bit machine, but in a 64-bit machine you could theoretically have terabytes of shared buffers. (How efficiently we could manage 'em remains to be seen.) Similarly, num_temp_buffers, work_mem, and maintenance_work_mem can be set above 2Gb on a 64-bit machine. Original patch from Koichi Suzuki, additional work by moi.
* Invoke mksafefunc and mkunsafefunc with :: decoration. This seems a goodTom Lane2005-08-20
| | | | | idea on consistency grounds, whether or not it really fixes bug #1831. Michael Fuhr
* Make GetMultiXactIdMembers() a public function.Tatsuo Ishii2005-08-20

* Add BackendXidGetPid().Tatsuo Ishii2005-08-20

* Repair problems with VACUUM destroying t_ctid chains too soon, and withTom Lane2005-08-20
| | | | | | | | | | | | insufficient paranoia in code that follows t_ctid links. (We must do both because even with VACUUM doing it properly, the intermediate state with a dangling t_ctid link is visible concurrently during lazy VACUUM, and could be seen afterwards if either type of VACUUM crashes partway through.) Also try to improve documentation about what's going on. Patch is a bit bulky because passing the XMAX information around required changing the APIs of some low-level heapam.c routines, but it's not conceptually very complicated. Per trouble report from Teodor and subsequent analysis. This needs to be back-patched, but I'll do that after 8.1 beta is out.
* Fix LRU/ALL description mismatch for GUC parameter.Bruce Momjian2005-08-19

* Consistently align comments in postgresql.conf, move some slightly toBruce Momjian2005-08-19
| | | | the right to stand out.
* Update some obsolete comments --- code is using t_self now, not t_ctid.Tom Lane2005-08-18
|
* Fix up LIMIT/OFFSET planning so that we cope with non-constant LIMITTom Lane2005-08-18
| | | | | | | | | | or OFFSET clauses by using estimate_expression_value(). The main advantage of this is that if the expression is a Param and we have a value for the Param, we'll use that value rather than defaulting. Also, fix some thinkos in the logic for combining LIMIT/OFFSET with an externally supplied tuple fraction (this covers cases like EXISTS(...LIMIT...)). And make sure the results of all this are shown by EXPLAIN. Per a gripe from Merlin Moncure.
* Add hint for to_char(interval) invalid format specifications.Bruce Momjian2005-08-18
|
* Fix to_char(interval) to return proper year and century values.Bruce Momjian2005-08-18
| | | | | | | | Fix to_char(interval) to return large year/month/day/hour values that are larger than possible timestamp values. Prevent to_char(interval) format specifications that make no sense, like Month. Clean up formatting.c code to more logically handle return lengths.
* Avoid an Assert failure if OuterUserId hasn't been set yet duringTom Lane2005-08-17
| | | | | AbortTransaction. This can happen if a backend's InitPostgres transaction fails (eg, because the given username is invalid). Per Alvaro.
* More formatting.c cleanups.Bruce Momjian2005-08-17
|
* Small cleanup.Bruce Momjian2005-08-17
|
* Adjust to_char/from_char code to use boolean "is_to_char" rather thanBruce Momjian2005-08-17
| | | | integer with flags.
* Fix declaration of dumpacl, per Alvaro.Tom Lane2005-08-17

* Update pgcvslog comment on how to find branch start time.Bruce Momjian2005-08-16
| | | | Run autoconf/autoheader in case someone forgot in the past.
* Reject operator names >= NAMEDATALEN characters. These will not workTom Lane2005-08-16
| | | | | anyway, and in assert-enabled builds you are likely to get an assertion failure. Backpatch as far as 7.3; 7.2 seems not to have the problem.
* Rename pg_stat_file columns to be more consistent. Split apart changeBruce Momjian2005-08-15
| | | | and creation columns to behave for Unix or Win32.
* Clean up recent patch for PL handler functions in pg_catalog: the patchTom Lane2005-08-15
| | | | | | caused PL languages and handlers to be dumped ALWAYS, even in the face of contrary --schema or --table switches. Adopt a slightly saner definition.
* Make createlang and droplang proof against weird search_path settingsTom Lane2005-08-15
| | | | by forcing search_path to be just pg_catalog.
* array_in() and array_recv() need to be more paranoid about validatingTom Lane2005-08-15
| | | | | | | | | their OID parameter. It was possible to crash the backend with select array_in('{123}',0,0); because that would bypass the needed step of initializing the workspace. These seem to be the only two places with a problem, though (record_in and record_recv don't have the issue, and the other array functions aren't depending on user-supplied input). Back-patch as far as 7.4; 7.3 does not have the bug.
* Allow the pgstat views to show toast tables as well as regular tablesTom Lane2005-08-15
| | | | | | | | (the stats system has always collected this info, but the views were filtering it out). Modify autovacuum so that over-threshold activity in a toast table can trigger a VACUUM of the parent table, even if the parent didn't appear to need vacuuming itself. Per discussion a month or so back about "short, wide tables".
* Clean up some stray remaining references to pg_shadow, pg_user, pg_group.Tom Lane2005-08-15
|
* Change pg_dump to use pg_roles instead of pg_user on 8.1 and up,Tom Lane2005-08-15
| | | | so that it will correctly dump owners of objects owned by non-login roles.
* Change standard_compliant_strings to standard_conforming_strings.Peter Eisentraut2005-08-14

* Update the createuser utility for the ROLEs world. Alvaro HerreraTom Lane2005-08-14
