intended to allow application authors to insulate themselves from
changes to the default value of 'default_with_oids' in future releases
of PostgreSQL.
This patch also fixes a bug in the earlier implementation of the
'default_with_oids' GUC variable: code in gram.y should not examine
the value of GUC variables directly due to synchronization issues.
variables, not just simple variables. This was foreseen in the original
coding of this routine, but not implemented until now. Responds to
performance gripe from Laurent Perez.
'simple' references another view that is not simple. Must recheck
conditions after performing recursive pullup. Per example from

ignore SIGPIPE from send() in libpq, but terminate on any other SIGPIPE,
unless the user installs their own signal handler.
This is a minor fix because the only time you get SIGPIPE from libpq's
send() is when the backend dies.
predicate tester. It can now deal with commuted clauses (for
instance, 4 < x implies x > 3), subclauses more complicated than
a simple Var (for example, upper(x) = 't' implies upper(x) > 'a'),
and <> operators (for example, x < 3 implies x <> 4). Still
only understands operators associated with btree opclasses, though.
Inspired by example from Martin Hampl.
pointer type when it is not necessary to do so.
For future reference, casting NULL to a pointer type is only necessary
when (a) invoking a function AND either (b) the function has no prototype
OR (c) the function is a varargs function.
parameters to be declared with names. pg_proc has a column to store
names, and CREATE FUNCTION can insert data into it, but that's all as
yet. I need to do more work on the pg_dump and plpgsql portions of the
patch before committing those, but I thought I'd get the bulky changes
in before the tree drifts under me.
initdb forced due to pg_proc change.
BackendFork/SSDataBase/pgstat) startup, to allow fork/exec calls to
closely mimic (the soon to be provided) Win32 CreateProcess equivalent
calls.

- Update comment in IsReservedName() to the present day
- Improve some variable & function names in commands/vacuum.c. I
was planning to rewrite this to avoid lappend(), but since I
still intend to do the list rewrite, there's no need for that.
- Update some smgr comments which seemed to imply that we still
forced all dirty pages to disk at commit-time.
- Replace some #ifdef DIAGNOSTIC code with assertions.
- Make the distinction between OS-level file descriptors and
virtual file descriptors a little clearer in a few comments
- Other minor comment improvements in the smgr code
