fields in JoinPaths --- turns out that we do need that after all :-(.
Also, rearrange planner so that only one RelOptInfo is created for a
particular set of joined base relations, no matter how many different
subsets of relations it can be created from.  This saves memory and
processing time compared to the old method of making a bunch of RelOptInfos
and then removing the duplicates.  Clean up the jointree iteration logic;
not sure if it's better, but I sure find it more readable and plausible
now, particularly for the case of 'bushy plans'.

Minor fix

from md.c.

regression tests so I prepared a set of expected
files to make things look OK.

There's also a file to account for minor variations
in the geopmetry output and a resultmap patch to
pull them all together.

With these changes PostgreSQL, from CVS, builds and
regression tests (runcheck) cleanly.

nonoverlap_sets() and is_subset() to list.c, where they should have lived
to begin with, and rename to nonoverlap_setsi and is_subseti since they
only work on integer lists.

fix suggested by Keith Parks.

lnext, to eliminate O(N^2) behavior with lots of indexquals.

extracting from an AND subclause just those opclauses that are relevant
for a particular index.  For example, we can now consider using an index
on x to process WHERE (x = 1 AND y = 2) OR (x = 2 AND y = 4) OR ...

it seems more suitable for the naming convention in libpq.

New function PQsetClientEncoding added. It makes possible to change
the client encoding on the fly without setting PGCLIENTENCODING.

FOREIGN KEY constraint during CREATE TABLE. Tnx to Stephan.

a FOREIGN KEY constraint.

Added constraint dumping capability to pg_dump (also from Stephan)

Fixed DROP TABLE -> RelationBuildTriggers: 2 record(s) not found for rel
error.

Fixed little error in gram.y I made the last days.

the cache context, it didn't bother to free the tuple that
CatalogIndexFetchTuple had allocated in the transaction context.
Do enough cache lookups in the same xact, and you start to notice...

Group and Unique use an arbitrary assumption that there will be about
10% as many groups as input tuples --- perhaps someday we can refine this.

syscache and relcache flushes).  Relcache entry rebuild now preserves
original tupledesc, rewrite rules, and triggers if possible, so that pointers
to these things remain valid --- if these things change while relcache entry
has positive refcount, we elog(ERROR) to avoid later crash.  Arrange for
xact-local rels to be rebuilt when an SI inval message is seen for them,
so that they are updated by CommandCounterIncrement the same as regular rels.
(This is useful because of Hiroshi's recent changes to process our own SI
messages at CommandCounterIncrement time.)  This allows simplification of
some routines that previously hacked around the lack of an automatic update.
catcache now keeps its own copy of tupledesc for its relation, rather than
depending on the relcache's copy; this avoids needing to reinitialize catcache
during a cache flush, which saves some cycles and eliminates nasty circularity
problems that occur if a cache flush happens while trying to initialize a
catcache.
Eliminate a number of permanent memory leaks that used to happen during
catcache or relcache flush; not least of which was that catcache never
freed any cached tuples!  (Rule parsetree storage is still leaked, however;
will fix that separately.)
Nothing done yet about code that uses tuples retrieved by SearchSysCache
for longer than is safe.

Bug fix for LongVarBinary -- begin transaction

we *always* rebuild, rather than deleting, an invalidated relcache entry
that has positive refcount.  Otherwise an SI cache overrun leads to
dangling Relation pointers all over the place!
