preprocessor and the library. This is useful for a number of reasons:
* The preprocessor and the library are in some cases installed in separate
packages and used by different classes of users.
* The library MO files need a different versioning scheme to account for the
soname.
* The makefiles are simpler, more robust, and easier to maintain this way.
(NLS web site was prone to break everytime a build rule changes.)
* Translators might choose to focus on the ecpglib, because that is more
user-facing.
* There was virtually no overlap, so nothing is lost.
and change auto_explain's custom GUC variables to be named auto_explain.xxx
not just explain.xxx. Per discussion in connection with the
pg_stat_statements patch, it seems like a good idea to have the convention
that custom variable classes are named the same as their defining module.
Committing separately since this should happen regardless of what happens
with pg_stat_statements itself.
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.
various display commands, not only for \z.
In passing, fix some infelicities in the newly added \d commands for SQL-MED
catalogs.

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.
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.
field needs to be included in equalRuleLocks() comparisons, else updates
will fail to propagate into relcache entries when they have positive
reference count (ie someone is using the relcache entry).
Per report from Alex Hunsaker.
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.)
This doesn't do any remote or external things yet, but it gives modules
like plproxy and dblink a standardized and future-proof system for
managing their connection information.

explicit cast to show the intended array type, we forgot to teach ruleutils.c
to print out such constructs properly. Found by noting bogus output from
recent changes in polymorphism regression test.
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.
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.
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.
