key call sites are changed, but most called functions are still oldstyle.
An exception is that the PL managers are updated (so, for example, NULL
handling now behaves as expected in plperl and plpgsql functions).
NOTE initdb is forced due to added column in pg_proc.

necessary to call isatty() for each and every received query.  That's
one less kernel call per query cycle ...

Most (nearly all) of the work was done by David Wragg <dpw@doc.ic.ac.uk>

He patched 6.5.3. I've updated it for 7.0RC5.

It works for MIT kerberos 1.1.1 (and previously for 1.0.6 as well).

I've got the patch against 6.5.3, plus kerberized RPMS.

other than the most common value in a column.  We had had 0.5, make it
0.1 to make it more likely that an indexscan will be chosen.  Really
need better statistics instead, but this should stem the bleeding
meanwhile ...

to an undecorated relation name (cf. example from Ed Loehr, 5/25/00).

since-closed file descriptors...

subsequent I/O attempts fail cleanly.  I'm speculating about failure
scenarios in which we do pq_close, then something in a proc_exit routine
opens a file (re-using that kernel FD number), then something else
fails and tries to write an elog message to the frontend ... message
ends up in opened file, oops.  No known examples of this but it seems
like a potential hole.

the oper field should be a valid Node structure so it can be dumped by
outfuncs.c without risk of coredump.  (We had been using a raw pointer
to character string, which surely is NOT a valid Node.)  This doesn't
cause any backwards compatibility problems for stored rules, since
raw unanalyzed parsetrees are never stored.

*last*, after all updating of system catalogs.  In old code, an error
detected during TypeRename left the relation hosed.  Also, add a call
to flush the relation's relcache entry, rather than trusting to shared
cache invalidation to flush it for us.

(it returns error with errno ECHILD upon successful completion of commands).
This fix ignores an error from system() if errno == ECHILD.

think that both sides of indexqual look like index keys.  An example is
create table inside (f1 float8 primary key);
create table outside (g1 float8, g2 float8);
select * from inside,outside where f1 = atan2(g1+1, g2);
ERROR:  ExecInitIndexScan: both left and right ops are rel-vars
(note that failure is potentially platform-dependent).  Solution is a
cleanup I had had in mind to make anyway: functional index keys should
be represented as Var nodes in the fixed indexqual, just like regular
index keys.

it exists) before testing 'using namespace std'.  This is necessary
on some C++ setups where the compiler won't take a 'using' until
you've included a header that mentions namespace std.  (Pretty braindead
if you ask me, but...)
