are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.

any other client connections that may exist (which would only happen if
another client is currently in the authentication cycle). This avoids
wastage of open descriptors in a child. It might also explain peculiar
behaviors like not closing connections when expected, since the kernel
will probably not signal EOF as long as some other backend is randomly
holding open a reference to the connection, even if the client went away
long since ...

elog(ERROR) not an Assert trap, since we've downgraded out-of-memory to
elog(ERROR) not a fatal error. Also, change the hard boundary from 256Mb
to 1Gb, just so that anyone who's actually got that much memory to spare
can play with TOAST objects approaching a gigabyte.

really matter for normal queries, but it sure does for queries invoked
repetitively inside SQL functions. Clean up some other grotty code

tests with simple SQL functions.

original table ('OLD' table) in its join tree if OLD is referenced by
either the rule action, the rule qual, or the original query qual that
will be added to the rule action. However, we only want one instance
of the original table to be included; so beware of the possibility that
the rule action already has a jointree entry for OLD.

any good way to fix it, short of a major querytree restructuring.

truncating to integer. Remove regress test that checks whether
4567890123456789 can be converted to float without loss; since that's
52 bits, it's on the hairy edge of failing with IEEE float8s, and indeed
rint seems to give platform-dependent results for it.

New code is protected by FixBTree bool flag setted to FALSE, so

to the use of getpwuid when running in standalone mode.
this patch allocates some persistent storage (using
strdup) to store the username obtained with getpwuid
in src/backend/main/main.c. this is necessary because
later on, getpwuid is called again (in ValidateBinary).
the man pages for getpwuid on SCO OpenServer, FreeBSD,
and Darwin all have words to this effect (this is from
the SCO OpenServer man page):
Note
====
All information is contained in a static area, so it must
be copied if it is to be saved. Otherwise, it may be
overwritten on subsequent calls to these routines.
in particular, on my platform, the storage used to hold
the pw_name from the first call is overwritten such that
it looks like an empty username. this causes a problem
later on in SetSessionUserIdFromUserName.
i'd assume this isn't a problem on most platforms because
getpwuid is called with the same UID both times, and the
same thing ends up happening to that static storage each
time. however, that's not guaranteed, and is _not_ what
happens on my platform (at least :).

than forcing 'plain'. This probably does not matter right now, but I
think it needs to be consistent with the regular (not-functional) index
case, where attstorage is copied from the underlying table. Clean up
some other dead and infelicitous code too.

Op, so that the sequence 'a_expr Op Op a_expr' will be parsed as
a_expr Op (Op a_expr) not (a_expr Op) Op a_expr as formerly. In other
words, prefer treating user-defined operators as prefix operators to
treating them as postfix operators, when there is an ambiguity.
Also clean up a couple of other infelicities in production priority
assignment --- for example, BETWEEN wasn't being given the intended
priority, but that of AND.

bothering to check the return value --- which meant that in case the
update or delete failed because of a concurrent update, you'd not find
out about it, except by observing later that the transaction produced
the wrong outcome. There are now subroutines simple_heap_update and
simple_heap_delete that should be used anyplace that you're not prepared
to do the full nine yards of coping with concurrent updates. In
practice, that seems to mean absolutely everywhere but the executor,
because *noplace* else was checking.

these work just fine with system attribute numbers. OK, it's a new
