for a good long while, I see no reason to maintain this original copy.

Remove all traces of the ODBC driver, which is now on GBorg as the psqlodbc
project ...

addition of a column list clause to the COPY command.  Spotted by
Martin Renters.

tighten foreign-key check (a self-reference should not prevent TRUNCATE),
improve error message, cause a relation's TOAST table to be truncated
along with the relation.

for repeat(). Again, somewhat off-the-cuff, so I might have missed
something...

test=# select lpad('xxxxx',1431655765,'yyyyyyyyyyyyyyyy');
ERROR:  Requested length too large
test=# select rpad('xxxxx',1431655765,'yyyyyyyyyyyyyyyy');
ERROR:  Requested length too large

(That's on a Unicode DB, haven't tested other encodings but AFAICT
this fix should still work.)

Good point -- that wouldn't cause incorrect results or a security
problem, but it would reject input that we should really accept.

Revised patch is attached.

constraints


The issue with finding and removing foreign key constraints is no longer
an issue, so please apply the attached.

It does NOT check for rules or on delete triggers (old style foreign
keys) as those are difficult to deal with (remove, truncate, re-add).

bytealike to TEXT.

This leaves like_escape_bytea() without anything to do, but I left it in
place in anticipation of the eventual bytea pattern selectivity
functions. If there is agreement that this would be the best long term
solution, I'll take it as a TODO for 7.4.

replace(string, from, to)
   -- replaces all occurrences of "from" in "string" to "to"
split(string, fldsep, column)
   -- splits "string" on "fldsep" and returns "column" number piece
to_hex(int32_num) & to_hex(int64_num)
   -- takes integer number and returns as hex string

Okay, libpq++ is moved to GBorg, and all traces of it have been removed
from the core repository ... I haven't *moved* the libpq++ files out of the
tree, mainly as we want to keep them in place for past branches ...

Peter, I think I've covered all the files I need, and re-ran autoconf to make
sure the configure file is in place properly ...

with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

Use off_t and size_t in pg_dump to handle file offset arithmetic correctly.

code is broken, but any small change in the output format might overrun
the buffer with the old size.

From Rod Taylor.

FOUND is set whenever a SELECT INTO returns > 0 rows, *or* when an
INSERT, UPDATE, or DELETE affects > 0 rows. We implemented the first
part of this behavior, but not the second.

I also improved the documentation on the various situations in which
FOUND can be set (excluding inside FOR loops, which I still need to
think about), and added some regression tests for this behavior.

It's also a necessity for an informational schema.  The catalog
(database) name is required in a number of places.
