Allow most expressions in BETWEEN clause. Allow all expressions if
surrounded by parentheses (but not all are meaningful).
Remove unused keywords ACL, APPEND, MERGE.
Requires a "make clean" to recompile all code since keyword numeric
assignments have changed with keyword removal.
Define boolean functions and operators for lseg <, <=, <>, >=, >.
Define functions and operators for closest point to lseg on box,
to line on lseg, to lseg on lseg.
Define function and operator for length of lseg.
Change length operator from '??' to '@-@'
(currently defined for path and lseg).
Define boolean functions for lseg <, <=, <>, >=, >
Define close_ls(), close_lseg(), lseg_length().
Write real code for close_sb(), close_pb(), inter_sb(), inter_lb().
Repair lseg_perp() which determines if two lsegs are perpendicular.
Repair lseg_dt() distance between two lsegs.
Note: close_sl() is clearly broken but will repair later
(calculating point on lseg rather than point on line).
Clean up the alpha port, remove the backend/port/alpha subdirectory
structure, and move the init_address_fixup() code directly into
backend/main/main.c with appropriate #ifdefs around it...
[This is a repost - it supercedes the previous one. It fixes the patch so
it doesn't bread aix port, plus there's a file missing out of the
original post because difforig doesn't pick up new files. It's now

This patch brings the JDBC driver up to the current protocol spec.
Basically, the backend now tells the driver what authentication scheme to
use.
The patch also fixes a performance problem with large objects. In the
buffer manager, each fastpath call was sending multiple Notifications to
the backend (sometimes more data in the form of notifications were being
sent than blob data!).
Make changes so that when the diff is done between 'expected' and 'results',
if an operating specific expected file exists, use that for the comparison.
This allows for "legit" differences between results, like the "Result too
large" message vs "Math result not representable" ...
Also, have the failed diffs get output to regression.diffs so that its easy to
view those tests that failed

I haven't had final confirmation from Peter yet, but the attached patch
needs to be applied for the Beta otherwise password and crypt
authentication just won't work.
It puts back the loop in libpq and also fixes a couple of problems with
maintaining compatability with pre-6.3 drivers.

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.

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.

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.

Fix a variety of locking problems like newer lock waiters getting

This is a patch to fix crashes in psql when executing queries from
an external file. The code also adds error checking to verify that
memory for "query" was allocated. The conditional for the block of
code was changed from "query == NULL" to "query_alloced == false".
The conditional, "query == NULL", was never true. This prevented
the memory being allocated for "query". A few lines later, an attempt
to write to an un-allocated memory area generated a SIGSEGV causing
the frontend to crash.
