I've been waiting (very patiently, I think) for a long time for outre joins,
views w/ joins and not the least, functions that can handle NULL's in an
orderly way.
A little anxious I started implementing these elements in my projects,

Todo:
1. Compact log files after checkpoint (save records of uncommitted
transactions and remove/archive others).
On the grounds that undo is not guaranteed anyway (concurrent heap access),
why not simply forget it, since above sounds rather expensive ?
The downside would only be, that

when you define a procedure in Interbase, you have the 'suspend'
instruction,
it suspend execution of the stored procedure and returns variables, then
come back to the procedure.

Title: select for update question
Hello,
As I understand it:
Issuing a select for update within a transaction will prevent other users from modifying data. (exclusive lock)

Tri-valued logic strikes again. Remember, NULL represents don't know,
which means could be anything. So, when you ask the system to return
values that are guaranteed not to be in a list, and that list contains
a NULL, the system returns nothing, since the NULL _could_ be equal to

Folks:
As I study the source of LockBuffer in bufmgr.c I came across
the following code snippet for the case of releasing a
shared (read) lock:
if (mode == BUFFER_LOCK_UNLOCK)
{
if (*buflock BL_R_LOCK)
{
(buf-r_locks)--;
if (!buf-r_locks)
*buflock = ~BL_R_LOCK;
Or I am missing something...
buflock is per-backend flag, it's not in shmem. Backend is
allowed only single lock per buffer.

Correct me if I am wrong, but both cases do present a problem currently
in 7.1. The WAL log will not remove any WAL files for transactions that
are still open (even after a checkpoint occurs). Thus if you do a bulk

You are not seriously saying that you like the rollback segments in Oracle.
They only cause trouble:

However, just remember that pg_class already has a row count that we

I was just suggesting we make that accurate if we can, even if we can

accurate anymore anyway. This is just an estimate, and in
