* Fix an oversight in my patch of a couple weeks ago that ensured a snapshotTom Lane2009-01-011-6/+12
| | | | | | | | | | is available during datatype input in Bind message processing. I put the PopActiveSnapshot() or equivalent just before PortalDefineQuery, which is an unsafe spot for it (in 8.3 and later) because we are carrying a plancache refcount that hasn't yet been assigned to the portal. Any error thrown there would result in leaking the refcount. It's not exactly likely that PopActiveSnapshot would throw an elog, perhaps, but it could happen. Reorder the code and add another comment warning not to do that.

* Add a WINDOW attribute to CREATE FUNCTION, and teach pg_dump about it,Tom Lane2008-12-319-18/+70
| | | | | | | | | | | so that user-defined window functions are possible. For the moment you'll have to write them in C, for lack of any interface to the WindowObject API in the available PLs, but it's better than no support at all. There was some debate about the best syntax for this. I ended up choosing the "it's an attribute" position --- the other approach will inevitably be more work, and the likely market for user-defined window functions is probably too small to justify it.
* Add some basic support for window frame clauses to the window-functionsTom Lane2008-12-3124-307/+757
| | | | | | | | patch. This includes the ability to force the frame to cover the whole partition, and the ability to make the frame end exactly on the current row rather than its last ORDER BY peer. Supporting any more of the full SQL frame-clause syntax will require nontrivial hacking on the window aggregate code, so it'll have to wait for 8.5 or beyond.

* Make a couple of small changes to the tuplestore API, for the benefit of theTom Lane2008-12-273-27/+65
| | | | | | | | | | | | upcoming window-functions patch. First, tuplestore_trim is now an exported function that must be explicitly invoked by callers at appropriate times, rather than something that tuplestore tries to do behind the scenes. Second, a read pointer that is marked as allowing backward scan no longer prevents truncation. This means that a read pointer marked as having BACKWARD but not REWIND capability can only safely read backwards as far as the oldest other read pointer. (The expected use pattern for this involves having another read pointer that serves as the truncation fencepost.)

* Don't use OidIsValid to check the return value of transformGenericOptions,Heikki Linnakangas2008-12-201-10/+10
| | | | | | because transformGenericOptions returns an array, not an Oid. I'm not sure if this fixes the crashes seen in buildfarm, but it should be fixed anyway.

| | | | | | | materialize-mode set results. Since it now uses the ReturnSetInfo node to hold internal state, we need to be sure to set up the node even when the immediately called function doesn't return set (but does have a set-valued argument). Per report from Anupama Aherrao.

* Don't reset pg_class.reltuples and relpages in VACUUM, if any pages wereHeikki Linnakangas2008-12-177-61/+94
| | | | | | | | | | | | | | | | | skipped. We could update relpages anyway, but it seems better to only update it together with reltuples, because we use the reltuples/relpages ratio in the planner. Also don't update n_live_tuples in pgstat. ANALYZE in VACUUM ANALYZE now needs to update pg_class, if the VACUUM-phase didn't do so. Added some boolean-passing to let analyze_rel know if it should update pg_class or not. I also moved the relcache invalidation (to update rd_targblock) from vac_update_relstats to where RelationTruncate is called, because vac_update_relstats is not called for partial vacuums anymore. It's more obvious to send the invalidation close to the truncation that requires it. Per report by Ned T. Crigler.
* The attached patch contains a couple of fixes in the existing probes andBruce Momjian2008-12-175-37/+79
| | | | | | | | | | | | | includes a few new ones. - Fixed compilation errors on OS X for probes that use typedefs - Fixed a number of probes to pass ForkNumber per the relation forks patch - The new probes are those that were taken out from the previous submitted patch and required simple fixes. Will submit the other probes that may require more discussion in a separate patch. Robert Lor

* Make heap_update() set newtup->t_tableOid correctly, for consistency withTom Lane2008-12-161-1/+2
| | | | | | | | | | the other major heapam.c functions. The only known consequence of this omission is that UPDATE RETURNING failed to return the correct value for "tableoid", as per report from KaiGai Kohei. Back-patch to 8.2. Arguably it's wrong all the way back; but without evidence of visible breakage before RETURNING was added, I'll desist from patching the older branches.

* Arrange for the pg_foo_is_visible and has_foo_privilege families of functionsTom Lane2008-12-153-8/+148
| | | | | | | | | | | to return NULL, instead of erroring out, if the target object is specified by OID and we can't find that OID in the catalogs. Since these functions operate internally on SnapshotNow rules, there is a race condition when using them in user queries: the query's MVCC snapshot might "see" a catalog row that's already committed dead, leading to a failure when the inquiry function is applied. Returning NULL should generally provide more convenient behavior. This issue has been complained of before, and in particular we are now seeing it in the regression tests due to another recent patch.

* Reduce the scaling factor for attstattarget to number-of-lexemes from 100Tom Lane2008-12-151-4/+4
| | | | | | | to 10, to compensate for the recent change in default statistics target. The original number was pulled out of the air anyway :-(, but it was picked in the context of the old default, so holding the default size of the MCELEM array constant seems the best thing. Per discussion.
