Gerhard Hintermayer, revised and documented by Tom Lane.

This patch also fixes a 'must fix' bug: libpgtcl's LISTEN/NOTIFY
support was broken by the recent changes to the PGnotify structure.
Guess that change wasn't quite so safe as we thought.

more flexible, and improve the error reporting.  Also, add documentation
for REPLACE RULE/VIEW.

The attached patch re-enables a bytea right hand argument (as compared
to a text right hand argument), and enables index usage, for bytea LIKE

not synonymous with CHECK (xxx IS NOT NULL) -- for example, consider
ALTER TABLE ADD PRIMARY KEY, which checks for 'NOT NULL', not a check
constraint.

Neil Conway

Alvaro Herrera

review/feedback if anyone is interested and can spend the time. But I'd
also love to get this committed and address changes as incremental
patches ;-), so if there are no objections, please apply.

Below I'll give a synopsis of the changes. More detailed descriptions
are now in a new doc directory under contrib/dblink. There is also a new

dblink.test.sql file which will give a pretty good overview of the
functions and their use.

Joe Conway

already fixed by You. However there were a few left and attached patch
should fix the rest of them.

I used StringInfo only in 2 places and both of them are inside debug
ifdefs. Only performance penalty will come from using strlen() like all
the other code does.

I also modified some of the already patched parts by changing
snprintf(buf, 2 * BUFSIZE, ... style lines to
snprintf(buf, sizeof(buf), ... where buf is an array.

Jukka Holappa

missing semicolons.

I also added a SELECT statement without a target list.

Manfred Koizar

into a separate parallel group. I can't confirm that this fixes the
problem for me (since it only occurs about one in ten or one in twenty
runs), but I think it's a good bet that it does...

Neil Conway

replace, split, and to_hex. The patch also moves encode and decode into
alphabetical order (since everything else in the table was).

function, connectby(), which can serve as a reference implementation for

the changes made in the last few days -- namely the ability of a
function to return an entire tuplestore, and the ability of a function
to make use of the query provided "expected" tuple description.

Description:

   connectby(text relname, text keyid_fld, text parent_keyid_fld,
     text start_with, int max_depth [, text branch_delim])
   - returns keyid, parent_keyid, level, and an optional branch string
   - requires anonymous composite type syntax in the FROM clause. See
     the instructions in the documentation below.

is an error, warning, etc.

pgmonitor.

Now log_min_error_statement uses it.

< * Evaluate AIX cs() spinlock macro for performance optimizations (Tatsuo)

during the regression test. The problem has been reproduced on two machine
but both of these are the same type of hardware and software. I also tried
to recreate the problem on other machines, on older version of AIX but I
couldn't.

After looked through pgsql-hackers mailing list, I focused on spin lock
issue to solve the problem. The easiest and may not be the best solution
for the problem is to give up HAS_TEST_AND_SET. This actually works.

One another and better solution for the problem is to use _check_lock() and
_clear_lock() as spin lock.  Important thing here is to define S_UNLOCK()
with _clear_lock().  This will solve the so called "Compiler bug" issue
someone wrote on the mailing list.

We have some other API such as cs(), compare_and_swap() and fetch_and_or()
to do test and set on AIX, but any of these didn't solve my problem.  I
wrote tiny testing program to see if we have any bug of these API of AIX,
but I couldn't see any problem except for compare_and_swap(). It seems that
you can not use compare_and_swap() for the purpose, as it would not work as
spin lock on any SMP machines I tested.  I don't know the reason why cs()
nor fetch_and_or()/fetch_and_and() will not work with PostgreSQL on p690.
These worked with my testing program on all machines I tested.

  Fixed support in the driver for notifications (added PGConnection.getNotifications()) - problem reported by Benjamin.Feinstein@guardent.com
  Worked around server problems with int8/int2 and constants; quote values when they are intended to bind to an int8/int2 column - reported by many
  Fixed bug in the Array interface with string parsing not handling escaped characters correctly - reported by devajx@yahoo.com
  Added workaround to support 'infinity' and '-infinity' for dates - reported bydmitry@openratings.com
  Fixed some performance issues with setBlob - reported by d.wall@computer.org
  Added support for using new prepared statements functionality in 7.3 (added PGStatement.setUseServerPrepare() and isUseServerPrepare() methods)

because c.h has sys/types.h.

Gavin Sherry, Neil Conway, and Tom Lane all got their hands dirty
on this one ...

(overlaying low byte of page size) and add HEAP_HASOID bit to t_infomask,
per earlier discussion.  Simplify scheme for overlaying fields in tuple
header (no need for cmax to live in more than one place).  Don't try to
clear infomask status bits in tqual.c --- not safe to do it there.  Don't
try to force output table of a SELECT INTO to have OIDs, either.  Get rid
of unnecessarily complex three-state scheme for TupleDesc.tdhasoids, which
has already caused one recent failure.  Improve documentation.
