Hi again!

It seems that the problem was the max_fsm_relations parameter which was
increased

I still do not understand why in the past I received always the message:

ERROR: out of shared memory

Is this an appropriate message for the need for increasing this parameter?

With best regards,

Sorin C.

Maybe you've got an application that is doing a BEGIN WORK, but never

doing a rollback or commit?
