I'm planing to upgrade from 7.2.1 to 7.3.4.

Right. And it waits on a semaphore, right? So there's no way to

I don't know the details of PostgreSQL's implementation, but it seems
that when lots of processes are waiting to update the same row, it
gets incredibly slow.
Hmm.

It's required. The clients are e-mail filters and they must reply

Either way, if the back-end is waiting on a semaphore, will it time
out the query and terminate? The problem is lots of waiting back-end
processes.

Dear All,
Is there any way by which we can restore the deleted column. Bcoz I have deleted a
column... and when I describe the contents I am seeing the column back again, but the
attribute name has been replaced with the system generated one.. and the structure
still remains the same.
