* Fix a bug in the original implementation of redundant-join-clause removal:Tom Lane2007-07-31
| | | | | | | | | clauses in which one side or the other references both sides of the join cannot be removed as redundant, because that expression won't have been constrained below the join. Per report from Sergey Burladyan. CVS HEAD does not contain this bug due to EquivalenceClass rewrite, but it seems wise to include the regression test for it anyway.
* If we're gonna use ExecRelationIsTargetRelation here, might as wellTom Lane2007-07-31
| | | | simplify a bit further.
* Fix security definer functions with polymorphic arguments. This case hasTom Lane2007-07-31
| | | | | never worked because fmgr_security_definer() neglected to pass the fn_expr information through. Per report from Viatcheslav Kalinin.
* Slight refactor for ExecOpenScanRelation(): we can useNeil Conway2007-07-27
| | | | | ExecRelationIsTargetRelation() to check if the relation is a target rel, rather than scanning through the result relation array ourselves.
* Update conformance information about bigint typePeter Eisentraut2007-07-27
| | | | found by Michael Glaesemann
* Remove FileUnlink(), which wasn't being used anywhere and interacted poorlyTom Lane2007-07-26
| | | | | | with the recent patch to log temp file sizes at removal time. Doesn't seem worth fixing since it's unused. In passing, make a few elog messages conform to the message style guide.
* Arrange to put TOAST tables belonging to temporary tables into special schemasTom Lane2007-07-25
| | | | | | | | | | | | | | named pg_toast_temp_nnn, alongside the pg_temp_nnn schemas used for the temp tables themselves. This allows low-level code such as the relcache to recognize that these tables are indeed temporary, which enables various optimizations such as not WAL-logging changes and using local rather than shared buffers for access. Aside from obvious performance benefits, this provides a solution to bug #3483, in which other backends unexpectedly held open file references to temporary tables. The scheme preserves the property that TOAST tables are not in any schema that's normally in the search path, so they don't conflict with user table names. initdb forced because of changes in system view definitions.

* Implement RETURN QUERY for PL/PgSQL. This provides some convenient syntaxNeil Conway2007-07-25
| | | | | | sugar for PL/PgSQL set-returning functions that want to return the result of evaluating a query; it should also be more efficient than repeated RETURN NEXT statements. Based on an earlier patch from Pavel Stehule.
* Fix predicate-proving logic to cope with binary-compatibility cases whenTom Lane2007-07-24
| | | | | | checking whether an IS NULL/IS NOT NULL clause is implied or refuted by a strict function. Per example from Dawid Kuroczko. Backpatch to 8.2 since this is arguably a performance bug.
* Silence compiler warning on mingwMagnus Hagander2007-07-24

* Make it possible, and default, for MingW to build with SSPI supportMagnus Hagander2007-07-24
| | | | | by dynamically loading the function that's missing from the MingW headers and library.
* Create a new dedicated Postgres process, "wal writer", which exists to writeTom Lane2007-07-24
| | | | | | | | | | | | | | and fsync WAL at convenient intervals. For the moment it just tries to offload this work from backends, but soon it will be responsible for guaranteeing a maximum delay before asynchronously-committed transactions will be flushed to disk. This is a portion of Simon Riggs' async-commit patch, committed to CVS separately because a background WAL writer seems like it might be a good idea independently of the async-commit feature. I rebased walwriter.c on bgwriter.c because it seemed like a more appropriate way of handling signals; while the startup/shutdown logic in postmaster.c is more like autovac because we want walwriter to quit before we start the shutdown checkpoint.
* Set a default autovacuum vacuum_cost_delay value of 20ms, to avoid excessiveAlvaro Herrera2007-07-24
| | | | | | | | I/O utilization, per discussion. While at it, lower the autovacuum vacuum and analyze threshold values to 50 tuples. It is a bit higher (i.e. more conservative) than what I originally proposed but much better than the old values for small tables.
* Just noticed that libpq thinks the maximum command tag length is 40,Tom Lane2007-07-23
| | | | | | whereas in the backend it's been 64 for some time. Hasn't mattered because no actual tags exceed 40 bytes, but for consistency they should be alike.
* Use PQExpBuffer for error message in fe-auth.c.Magnus Hagander2007-07-23
| | | | | In passing, change functions that passedin both PGconn and parts of it to just pass in the PGconn.
* Reword paragraph about the autovacuum_max_workers setting. Patch fromAlvaro Herrera2007-07-23
| | | | Jim Nasby.

* SSPI authentication on Windows. GSSAPI compatible client when doing KerberosMagnus Hagander2007-07-23
| | | | | | | against a Unix server, and Windows-specific server-side authentication using SSPI "negotiate" method (Kerberos or NTLM). Only builds properly with MSVC for now.
* Fix elog.c to avoid infinite recursion (leading to backend crash) whenTom Lane2007-07-21
| | | | | | | | | | log_min_error_statement is active and there is some problem in logging the current query string; for example, that it's too long to include in the log message without running out of memory. This problem has existed since the log_min_error_statement feature was introduced. No doubt the reason it wasn't detected long ago is that 8.2 is the first release that defaults log_min_error_statement to less than PANIC level. Per report from Bill Moran.
* Provide a bit more high-level documentation for the GEQO planner.Tom Lane2007-07-21
| | | | Per request from Luca Ferrari.

* Fix WAL replay of truncate operations to cope with the possibility that theTom Lane2007-07-20
| | | | | | | | | truncated relation was deleted later in the WAL sequence. Since replay normally auto-creates a relation upon its first reference by a WAL log entry, failure is seen only if the truncate entry happens to be the first reference after the checkpoint we're restarting from; which is a pretty unusual case but of course not impossible. Fix by making truncate entries auto-create like the other ones do. Per report and test case from Dharmendra Goyal.
* Capitalize language key words in error messagesPeter Eisentraut2007-07-20

* On second thought, the tests for what to do with stderr output are aTom Lane2007-07-19
| | | | | lot more sensible if we check the chunk-output case first. Not back-patched since it's just a cosmetic improvement.
* Make replace(), split_part(), and string_to_array() behave somewhat sanelyTom Lane2007-07-19
| | | | | | | | | when handed an invalidly-encoded pattern. The previous coding could get into an infinite loop if pg_mb2wchar_with_len() returned a zero-length string after we'd tested for nonempty pattern; which is exactly what it will do if the string consists only of an incomplete multibyte character. This led to either an out-of-memory error or a backend crash depending on platform. Per report from Wiktor Wodecki.
* Only use the pipe chunking protocol if we know the syslogger shouldAndrew Dunstan2007-07-19
| | | | | | | be catching stderr output, and we are not ourselves the syslogger. Otherwise, go directly to stderr. Bug noticed by Tom Lane. Backpatch as far as 8.0.
* Adjust configure script to print the bison and flex versions in use.Tom Lane2007-07-19
| | | | Minor rearrangements to make a few tests in a more logical order.
* Fix an old thinko in SS_make_initplan_from_plan, which is used when optimizingTom Lane2007-07-18
| | | | | | | | a MIN or MAX aggregate call into an indexscan: the initplan is being made at the current query nesting level and so we shouldn't increment query_level. Though usually harmless, this mistake could lead to bogus "plan should not reference subplan's variable" failures on complex queries. Per bug report from David Sanchez i Gregori.

* Fix incorrect optimization of foreign-key checks. When an UPDATE on theTom Lane2007-07-17
| | | | | | | | | | | | | | referencing table does not change the tuple's FK column(s), we don't bother to check the PK table since the constraint was presumably already valid. However, the check is still necessary if the tuple was inserted by our own transaction, since in that case the INSERT trigger will conclude it need not make the check (since its version of the tuple has been deleted). We got this right for simple cases, but not when the insert and update are in different subtransactions of the current top-level transaction; in such cases the FK check would never be made at all. (Hence, problem dates back to 8.0 when subtransactions were added --- it's actually the subtransaction version of a bug fixed in 7.3.5.) Fix, and add regression test cases. Report and fix by Affan Salman.

* Fix outfuncs.c to dump A_Const nodes representing NULLs correctly. This hasTom Lane2007-07-17
