There's now only one transition value and transition function.
NULL handling in aggregates is a lot cleaner.  Also, use Numeric
accumulators instead of integer accumulators for sum/avg on integer
datatypes --- this avoids overflow at the cost of being a little slower.
Implement VARIANCE() and STDDEV() aggregates in the standard backend.

Also, enable new LIKE selectivity estimators by default.  Unrelated
change, but as long as I had to force initdb anyway...

seems to be busted though ...

link needs to specify -lc but doesn't.  Quick hack to make it better.

stuff, but fixing the bug that existed in reporting the constraint name
changes the error line.  Patch to expected output enclosed.

The .DEFAULT rule in backend/Makefile is harmful -- removed.
Replace `::' rules by `:'.

Read templates after compiler is detected. Convert all templates to real
shell scripts. Rename bsd->openbsd, alpha->osf.

AlterTableAddConstraint.  The major changes from the last patch
are that it should hopefully check for references to temp tables
(not in the shadow case, but at defination time) from permanent tables in
foreign keys and refuse them and that it doesn't allow the table(s)
being constrained to be views (because those cases don't currently
work).

pass-by-ref data types --- eg, an index on lower(textfield) --- no longer
leak memory during index creation or update.  Clean up a lot of redundant
code ... did you know that copy, vacuum, truncate, reindex, extend index,
and bootstrap each basically duplicated the main executor's logic for
extracting information about an index and preparing index entries?
Functional indexes should be a little faster now too, due to removal
of repeated function lookups.
CREATE INDEX 'opt_type' clause is deimplemented by these changes,
but I haven't removed it from the parser yet (need to merge with
Thomas' latest change set first).

 Include updates for the comment.sql regression test.
Implement SET SESSION CHARACTERISTICS and SET DefaultXactIsoLevel.
Implement SET SESSION CHARACTERISTICS TRANSACTION COMMIT
 and SET AutoCommit in the parser only.
 Need to add code to actually do something.
Implement WITHOUT TIME ZONE type qualifier.
Define SCHEMA keyword, along with stubbed-out grammar.
Implement "[IN|INOUT|OUT] [varname] type" function arguments
 in parser only; INOUT and OUT throws an elog(ERROR).
Add PATH as a type-specific token, since PATH is in SQL99
 to support schema resource search and resolution.

 build in this directory otherwise :(

 This will ensure building parse.h for commands, though this is also
 covered with other build rules.

Fix references to pg_hba.conf(5) since that is no longer a man page.
Make minor repairs to "Compatibility" subsections.

Add information on SET SESSION CHARACTERISTICS.
Fix references to pg_hba.conf(5) since that is no longer a man page.

Make Gen_fmgrtab.sh reasonably robust against concurrent invocation.

them, but forgot to attach relevant restriction clauses, so that the
plan represented a scan over the whole table with restrictions applied
as qpquals not indexquals.  Another day, another bug...

* the result is not recorded anywhere
* the result is not used anywhere
* the result is only used in some places, whereas others have been getting away with it
* the result is used improperly

Also make command line options handling a little better (e.g., --disable-locale,
while redundant, should really still *dis*able).

to make AIX'ers happy with the changes to the version.o ?

Together with the patch I sent Tom, AIX now regresses ok.

Thanx

Rename settings net_server to tcpip_socket, max_backends to max_connections
Add --help and --version to postmaster, reformat help output

Doesn't anyone around here run regression tests before submitting
patches, or before committing them?

memory contexts.  Currently, only leaks in expressions executed as
quals or projections are handled.  Clean up some old dead cruft in
executor while at it --- unused fields in state nodes, that sort of thing.

in-chunk leaks, overwrite-next-chunk leaks and overwrite block-freeptr leaks.

A in-chunk leak --- if something overwrite space after wanted (via palloc()
size, but it is still inside chunk. For example

        x = palloc(12);         /* create 16b chunk */
        memset(x, '#', 13);

this leak is in the current source total invisible, because chunk is 16b and
leak is in the "align space".

 For this feature I add data_size to StandardChunk, and all memory which go
from AllocSetAlloc() is marked as 0x7F.

 The MemoryContextCheck() is compiled '#ifdef USE_ASSERT_CHECKING'.

I add this checking to 'tcop/postgres.c' and is active after each backend
query, but it is probably not sufficient, because some MemoryContext exist
only during memory processing --- will good if someone who known where
it is needful (Tom:-) add it for others contexts;
 A problem in the current source is that we have still some malloc()
allocation that is not needful and this allocation is total invisible for
all context routines. For example Dllist in backend (pretty dirty it is in
catcache where values in Dllist are palloc-ed, but list is malloc-ed).
--- and BTW. this Dllist design stand in the way for query cache :-)

 Tom, if you agree I start replace some mallocs.

 BTW. --- Tom, have you idea for across transaction presistent allocation for
          SQL functions? (like regex - now it is via malloc)


 I almost forget. I add one if() to AllocSetAlloc(), for 'size' that are
greater than ALLOC_BIGCHUNK_LIMIT is not needful check AllocSetFreeIndex(),
because 'fidx' is always 'ALLOCSET_NUM_FREELISTS - 1'. It a little brisk up
allocation for very large chunks. Right?

A patch for CVS is attached, and I have amended my BLOB dumping version
appropriately.
