type different from input type but are expecting ExecAgg to insert the
first non-null input as the starting transition value.  This has always
been verboten, but wasn't checked for until now...

NOTE: this implementation of tcl_avg() fails with 'divide by zero'
for zero input rows.  It ought to return NULL, but pltcl does not
currently provide a way to do that, so I'm leaving the problem unsolved
for now.

bothering to clean up the resulting warnings ...

documentation. Therefore it's now installed by default. If there is no
documentation to be found (i.e., you are not using the distribution)
then this step is skipped.

Add --docdir option to configure to control installation directory.

portable.  Seems to have been added for O_BINARY, which is only needed
for __CYGWIN32__, so include it here only in that case.

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).

Stephan SzaboThis should be a slighly more complete patch for commands/command.c

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
