precision storage format. Previously applied the same math as used for the
 64-bit integer storage format case, which was wrong.
 Problem introduced recently when the 64-bit storage format was
 implemented.

a multicolumn-capable index AM *must* support nulls in index columns
after the first one.

that would do the wrong thing with BLOB OIDs exceeding 2G.

one immediately upon forking to handle a new connection, and one after
the authentication cycle is finished.  Per today's pggeneral discussion.

having names conflicting with system objects will work --- the search
path is now user-schema, pg_catalog rather than implicitly the other way
around.  Note this requires being careful to explicitly qualify references
to system names whenever pg_catalog is not first in the search path.
Also, add support for dumping ACLs of schemas.

From Joe Conway.

where the latter is made slightly larger to allow for in-memory tuples
containing resjunk attributes.  Responds to today's complaint that one
cannot UPDATE a table containing the allegedly-legal maximum number of
columns.

Also, apply Manfred Koizar's recent patch to avoid extra alignment padding
when there is a null bitmap.  This saves bytes in some cases while not
creating any backward-compatibility problem AFAICS.

and just slow down normal operations (only fractionally, but a cycle saved
is a cycle earned).  Improve documentation of AMI_OVERRIDE behavior.

wasn't seen before, maybe the Tcl compiler flags were less strict.

transaction, so as to avoid returning them out of the index AM.  Saves
repeated heap_fetch operations on frequently-updated rows.  Also detect
queries on unique keys (equality to all columns of a unique index), and
don't bother continuing scan once we have found first match.

Killing is implemented in the btree and hash AMs, but not yet in rtree
or gist, because there isn't an equally convenient place to do it in
those AMs (the outer amgetnext routine can't do it without re-pinning
the index page).

Did some small cleanup on APIs of HeapTupleSatisfies, heap_fetch, and
index_insert to make this a little easier.

system, not Tcl-provided one.

Make sure export file, if any, is cleaned.

Tcl configuration is now read directly in configure and recorded in
Makefile.global.  This eliminates some duplicate efforts and allows
for easier hand-editing of the results, if necessary.

to do profiling on Cygwin, per report from Dave Page.

exemplified by bug #671.  Moving the storage to relcache turned out to
be a bad idea because relcache might decide to discard the info.  Instead,
open and close the relcache entry on each sequence operation, and use
a record of the current XID to discover whether we already hold
AccessShareLock on the sequence.

function body (and other properties) as a function in the language
is created.  This generalizes ad hoc code that already existed for
the built-in languages.

The validation now happens after the pg_proc tuple of the new function
is created, so it is possible to define recursive SQL functions.

Add some regression test cases that cover bogus function definition
attempts.

reference count.  This avoids leaving dangling pointers around, as in
recent bug report against sequences (bug# 671).

  CREATE VIEW as SELECT CTID, ....

2) Supprt ARD precision/scale and SQL_C_NUEMRIC.
3) Minimal implementation of SQLGetDiagField().
4) SQLRowCount() reports the result of SQLSetPos and SQLBulkOperation.
5) int8 -> SQL_NUMERIC for Microsoft Jet.
6) Support isolation level change.
7) ODBC3.0 SQLSTATE code.
8) Append mode log files.

a frozen (copied) snapshot too.  Move execMain's snapshot copying code
out into a subroutine in case we find other places that need it.

or appropriate, since the snapshot that will be used by the cursor was
frozen when ExecutorStart was run for it.

in snapshots, per my proposal of a few days ago.  Also, tweak heapam.c
routines (heap_insert, heap_update, heap_delete, heap_mark4update) to
be passed the command ID to use, instead of doing GetCurrentCommandID.
For catalog updates they'll still get passed current command ID, but
for updates generated from the main executor they'll get passed the
command ID saved in the snapshot the query is using.  This should fix
some corner cases associated with functions and triggers that advance
current command ID while an outer query is still in progress.

be smarter about parentheses in read_sql_construct().  Sigh.

yesterday's proposal to pghackers.  Also remove unnecessary parameters
to heap_beginscan, heap_rescan.  I modified pg_proc.h to reflect the
new numbers of parameters for the AM interface routines, but did not
force an initdb because nothing actually looks at those fields.
