It's missing in older versions too, but it doesn't seem worth
back-porting. All negative are just harmlessly treated as "no limit", and
tightening the check might even brake an application that relies on it.

encoding conversion functions.  These are not can't-happen cases because
it's possible to create a conversion with the wrong conversion function
for the specified encoding pair.  That would lead to an Assert crash in
an Assert-enabled build, or incorrect conversion otherwise, neither of
which is desirable.  This would be a DOS issue if production databases
were customarily built with asserts enabled, but fortunately that's not so.
Per an observation by Heikki.

Back-patch to all supported branches.

Per Tommy Gildseth <tommy.gildseth@usit.uio.no> report

data should be restored.
Backpatch only for 8.3 because previous versions haven't such layer.

it's implemented, but accepted too much/too little compared to
the API documentation.

(particularly autovacuum) to do the same without necessarily having to open
and lock a table.

pages were marked as clean as well. The idea is to avoid defeating OS
readahead by skipping a page here and there, and also makes it less likely
that we miss an opportunity to advance relfrozenxid, for the sake of only
a few skipped pages.

Original patch from Hiroshi Inoue.

For some reason it broke OpenBSD compile even when it's inside a
#ifdef WIN32 block.....

case that the command is rewritten into another type of command. The old
behavior to return the command tag of the last executed command was
pretty surprising. In PL/pgSQL, for example, it meant that if a command
was rewritten to a utility statement, FOUND wasn't set at all.

Also, if linked against other versions than the default MSVCRT library
(for example the MSVC build which links against MSVCRT80), also update
the cache in the default MSVCRT at the same time.

This should fix the issues with setting LC_MESSAGES on the MSVC build.

Original patch from Hiroshi Inoue and Hiroshi Saito, much rewritten
by me.

responsible for calling RestoreBkpBlocks(). They know better what kind of a
lock they need.

At the moment, this just moves things around with no functional change, but
makes the hot standby patch that's under review cleaner.

CREATE/ALTER/DROP USER MAPPING are now allowed either by the server owner or
by a user with USAGE privileges for his own user name.  This is more or less
what the SQL standard wants anyway (plus "implementation-defined")

Hide information_schema.user_mapping_options.option_value, unless the current
user is the one associated with the user mapping, or is the server owner and
the mapping is for PUBLIC, or is a superuser.  This is to protect passwords.

Also, fix a bug in information_schema._pg_foreign_servers, which hid servers
using wrappers where the current user did not have privileges on the wrapper.
The correct behavior is to hide servers where the current user has no
privileges on the server.
