number in the data structure so that we can give at least a minimally
useful idea of where the mistake is when we issue syntax error messages.
Move the ClientAuthentication() call to where it should have been in
the first place, so that postmaster memory releasing can happen in a
reasonable place also. Update obsolete comments, correct one real bug
(auth_argument was not picked up correctly).

more care with resjunk tlist entries than it was doing. The original
coding ignored resjunk entries entirely, but a resjunk entry that is
in either the distinctClause or sortClause lists indicates that DISTINCT
ON was used. It's important for ruleutils.c to get this right, else we
may dump views using DISTINCT ON incorrectly.

has a DISTINCT ON clause, per bug report from Anthony Wood. While at it,
improve the DISTINCT-ON-clause recognizer routine to not be fooled by out-
of-order DISTINCT lists.

echo "command" | postgres

This makes the script more legible (IMHO anyway) by reducing the need
to escape quotes, and allows us to execute successive SQL commands in
a single standalone-backend run, rather than needing to start a new
standalone backend for each command. With all the CREATE VIEWs that
are getting done now, this makes for a rather substantial reduction
in the runtime of initdb. (Some of us do initdb often enough to care
how long it runs ;-).)

connection implementations (org.postgresql.jdbc[1|2].Connection) into
their superclass (org.postgresql.Connection).
It also changes the close() methods of Connection and PG_Stream, so that
PG_Stream no longer is responsible for sending the termination packet 'X'
to the backend. I figured that protocol-level stuff like that belonged in
Connection more than in PG_Stream.

Here's a patch against the current CVS. The changes from the previous
patch are mostly related to the changed interface for PG_Stream.

changes on this new source to make non-blocking connection work. I
tested it, and PQSendQuery and PQGetResult are working fine.
In win32.h I added one line:

functions do not set errno, so some normal conditions are treated as
fatal errors. e.g. fetching large tuples fails, as at some point recv()
returns EWOULDBLOCK. here's a patch, which replaces errno with
WSAGetLastError(). i've tried to to affect non-win32 code.

rather than deleting them only to have to create more. Steady state
is 2*CHECKPOINT_SEGMENTS + WAL_FILES + 1 segment files, which will
simply be renamed rather than constantly deleted and recreated.
To make this safe, added current XLOG file/offset number to page
header of XLOG pages, so that an un-overwritten page from an old
incarnation of a logfile can be reliably told from a valid page.
This change means that if you try to restart postmaster in a CVS-tip
database after installing the change, you'll get a complaint about
bad XLOG page magic number. If you don't want to initdb, run
contrib/pg_resetxlog (and be sure you shut down the old postmaster
cleanly).

since the added qual could change the set of rows that get past the
LIMIT. Per discussion on pgsql-sql 7/15/01.

Note: I didn't force an initdb, figuring that one today was enough.
However, there is a new function in pg_proc.h, and pg_dump won't be
able to dump partial indexes until you add that function.

per previous discussion on pghackers. Most of the duplicate code in
different AMs' ambuild routines has been moved out to a common routine
in index.c; this means that all index types now do the right things about
inserting recently-dead tuples, etc. (I also removed support for EXTEND
INDEX in the ambuild routines, since that's about to go away anyway, and
it cluttered the code a lot.) The retail indextuple deletion routines have
been replaced by a "bulk delete" routine in which the indexscan is inside
the access method. I haven't pushed this change as far as it should go yet,
but it should allow considerable simplification of the internal bookkeeping
for deletions. Also, add flag columns to pg_am to eliminate various
hardcoded tests on AM OIDs, and remove unused pg_am columns.
Fix rtree and gist index types to not attempt to store NULLs; before this,
gist usually crashed, while rtree managed not to crash but computed wacko
bounding boxes for NULL entries (which might have had something to do with
the performance problems we've heard about occasionally).
Add AtEOXact routines to hash, rtree, and gist, all of which have static
state that needs to be reset after an error. We discovered this need long
ago for btree, but missed the other guys.
Oh, one more thing: concurrent VACUUM is now the default.

null terminated strings. The FE/BE protocol sends in some cases null
terminated strings to the client. The docs for the FE/BE protocol state
that there is no limit on the size of a null terminated string sent to
the client and a client should be coded using an expanding buffer to
deal with large strings. The old code did not do this and gave an error
if a null terminated string was greater than either 4 or 8K. It appears
that with the advent of TOAST very long SQL statements are becoming more
common, and apparently some error messages from the backend include the
SQL statement thus easily exceeding the 8K limit in the old code.
In fixing I also cleaned up some calls in the JDBC fastpath code that
were not doing character set conversion under multibyte, and removed
some methods that were no longer needed. I also removed a potential
threading problem with a shared variable that was being used in
Connection.java.
Thanks to Steve Wampler for discovering the problem and sending the
initial diffs that were the basis of this patch.
thanks,

VACUUM code to allow more code to be shared between full and lazy VACUUM.
Minor code cleanups and added comments for TransactionId manipulations.
