Attached is the patch to fix the warning messages from my code.  I also
fixed one which wasn't my code.  Apart from the usual warnings about the
bison/yacc generated code I only have one other warning message.  This
is in gramm.y around line 2234.  I wasn't sure of the fix.

I've also replaced all the calls to free() in gramm.y to calls to
pfree().  Without these I was getting backend crashes with GRANT.  This
might already have been fixed.

I've patched pg_dump.c and createdb to add support for password
authentication, using the '-u' switch as in psql. I have updated also the
man pages.

This has a problem when using any authentication other than trust or
ident.

Anything using libpq will hang, because the client will go into a loop
while connecting. The following patch simply comments out two lines (a do
and a while), removing the loop. Going through the new scheme, I can't see
why this do..while loop is in there.

offsetof() addition to local socket size.

(void) change for aix and hp compilers.

Cleanup patches for previous protocol changes patch

I've completed the patch to fix the protocol and authentication issues I
was discussing a couple of weeks ago.  The particular changes are:

- the protocol has a version number
- network byte order is used throughout
- the pg_hba.conf file is used to specify what method is used to
  authenticate a frontend (either password, ident, trust, reject, krb4
  or krb5)
- support for multiplexed backends is removed
- appropriate changes to man pages
- the -a switch to many programs to specify an authentication service
  no longer has any effect
- the libpq.so version number has changed to 1.1

The new backend still supports the old protocol so old interfaces won't
break.

I have always been under the impression that NULL is not equal to
NULL and that NULL is not equal to anything else either.  If this
is the case, then this patch is correct.

If NULL _is_ equal to NULL, then I think there are other problems
in the Group By logic.

PostgreSQL type extensions for IP and MAC addresses.

I needed to record IP and MAC level ethernet addresses in a data
base, and I really didn't want to store them as plain strings, with
no enforced error checking, so I put together the accompanying code
as my first experiment with adding a data type to PostgreSQL.  I
then thought that this might be useful to others, both directly and
as a very simple example of how to do this sort of thing, so here
it is, in the hope that it will be useful.

Small patch for sparc solaris/tas()

This patch solves the problem with multiple order by columns, with the
first one having NULL values.

Hi -- a couple of small items concerning the January 23rd snapshot:
the inclusion of the Kerberos stuff in one Makefile, a "leading tab"
cleanup in another, and a fix for a typo in the configure script.
