* Fix a couple of snapshot management bugs in the new ResourceOwner world:Alvaro Herrera2008-12-04
| | | | | | | | | | | non-writable large objects need to have their snapshots registered on the transaction resowner, not the current portal's, because it must persist until the large object is closed (which the portal does not). Also, ensure that the serializable snapshot is recorded by the transaction resource owner too, even when a subtransaction has changed the current resource owner before serializable is taken. Per bug reports from Pavan Deolasee.

* Utilize the visibility map in autovacuum, too. There was an oversight inHeikki Linnakangas2008-12-04
| | | | | | | | | the visibility map patch that because autovacuum always sets VacuumStmt->freeze_min_age, visibility map was never used for autovacuum, only for manually launched vacuums. This patch introduces a new scan_all field to VacuumStmt, indicating explicitly whether the visibility map should be used, or the whole relation should be scanned, to advance relfrozenxid. Anti-wraparound vacuums still need to scan all pages.

* Properly unregister OpenSSL callbacks when libpq is done withMagnus Hagander2008-12-03
| | | | | | | | | | | | | | it's connection. This is required for applications that unload the libpq library (such as PHP) in which case we'd otherwise have pointers to these functions when they no longer exist. This needs a bit more testing before we can consider a backpatch, so not doing that yet. In passing, remove unused functions in backend/libpq. Bruce Momjian and Magnus Hagander, per report and analysis by Russell Smith.

* Introduce visibility map. The visibility map is a bitmap with one bit perHeikki Linnakangas2008-12-03
| | | | | | | | | | | | | | | | | | heap page, where a set bit indicates that all tuples on the page are visible to all transactions, and the page therefore doesn't need vacuuming. It is stored in a new relation fork. Lazy vacuum uses the visibility map to skip pages that don't need vacuuming. Vacuum is also responsible for setting the bits in the map. In the future, this can hopefully be used to implement index-only-scans, but we can't currently guarantee that the visibility map is always 100% up-to-date. In addition to the visibility map, there's a new PD_ALL_VISIBLE flag on each heap page, also indicating that all tuples on the page are visible to all transactions. It's important that this flag is kept up-to-date. It is also used to skip visibility tests in sequential scans, which gives a small performance gain on seqscans.

* Minor code embellishments.Alvaro Herrera2008-12-02

* Fix an oversight in the code that makes transitive-equality deductions fromTom Lane2008-12-01
| | | | | | | | | | | | | | | | | | | | outer join clauses. Given, say, ... from a left join b on a.a1 = b.b1 where a.a1 = 42; we'll deduce a clause b.b1 = 42 and then mark the original join clause redundant (we can't remove it completely for reasons I don't feel like squeezing into this log entry). However the original implementation of that wasn't bulletproof, because clause_selectivity() wouldn't honor this_selec if given nonzero varRelid --- which in practice meant that it worked as desired *except* when considering index scan quals. Which resulted in bogus underestimation of the size of the indexscan result for an inner indexscan in an outer join, and consequently a possibly bad choice of indexscan vs. bitmap scan. Fix by introducing an explicit test into clause_selectivity(). Also, to make sure we don't trigger that test in corner cases, change the convention to be that this_selec > 1, not this_selec = 1, means it's been marked redundant. Per trouble report from Scara Maccai. Back-patch to 8.2, where the problem was introduced.
* Modify the new to_timestamp implementation so that end-of-format-stringHeikki Linnakangas2008-12-01
| | | | | | | | | | | is treated like a non-digit separator. This fixes the inconsistency in examples like: to_timestamp('2008-01-2', 'YYYY-MM-DD') -- didn't work and to_timestamp('2008-1-02', 'YYYY-MM-DD') -- did work
* Ensure that the contents of a holdable cursor don't depend on out-of-lineTom Lane2008-12-01
| | | | | | | | | | | toasted values, since those could get dropped once the cursor's transaction is over. Per bug #4553 from Andrew Gierth. Back-patch as far as 8.1. The bug actually exists back to 7.4 when holdable cursors were introduced, but this patch won't work before 8.1 without significant adjustments. Given the lack of field complaints, it doesn't seem worth the work (and risk of introducing new bugs) to try to make a patch for the older branches.

* Clean up the API for DestReceiver objects by eliminating the assumptionTom Lane2008-11-30
| | | | | | | | | | | | that a Portal is a useful and sufficient additional argument for CreateDestReceiver --- it just isn't, in most cases. Instead formalize the approach of passing any needed parameters to the receiver separately. One unexpected benefit of this change is that we can declare typedef Portal in a less surprising location. This patch is just code rearrangement and doesn't change any functionality. I'll tackle the HOLD-cursor-vs-toast problem in a follow-on patch.
* Add a "LIKE = typename" clause to CREATE TYPE for base types. This allowsTom Lane2008-11-30
| | | | | | | | | | | the basic representational details (typlen, typalign, typbyval, typstorage) to be copied from an existing type rather than listed explicitly in the CREATE TYPE command. The immediate reason for this is to provide a simple solution for add-on modules that want to define types represented as int8, float4, or float8: as of 8.4 the appropriate PASSEDBYVALUE setting is platform-specific and so it's hard for a SQL script to know what to do. This patch fixes the contrib/isn breakage reported by Rushabh Lathia.
* Remove inappropriate memory context switch in shutdown_MultiFuncCall().Tom Lane2008-11-30
| | | | | | | This was a thinko introduced in a patch from last February; it results in memory leakage if an SRF is shut down before the actual end of query, because subsequent code will be running in a longer-lived context than it's expecting to be.

Check if we can connect to the port before starting our own postmaster, to detect some other server already running there. To simplify the code, drop --temp-port option and use --port for both temp-install and pre-installed case.

The previous coding would just silently discard portions of the intended buffer contents, as exhibited in trouble report from Sam Mason. Also, tweak psql's main loop to correctly detect and report such overruns. There's probably much more that should be done in this line, but this is a start.

As noted by Peter, adding this variable created a risk of unexpected connection failures when talking to older server versions, and since it doesn't do anything you can't do with PGOPTIONS, it doesn't seem really necessary.
