Hi all,

Hi,
I found patch for 8.4:
When reporting a deadlock, report the text of all queries involved in the

Pozdrawiam,
I have 8.3 database with non-trivial table (~ 80million rows, but the
rows are just two integers).
I need to add not null on one of the columns, but it seems to require

I tried with some indexes, but I can't get the time to something

either I am incredibly lucky(I wish) or something is going

Of course it does. If you want a constraint added to the table, the

You coul patch pg_attribute directly. I'm not sure if that's still safe
in current versions, though.
