select from a table with attrs (a int, b char(20))
crashed in bpcharout() (palloc of -1 bytes). But a table
with attrs (a int, b varchar(20)) worked.

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 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).
[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
attached. peter]
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!).
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.
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.
