How can it be, that pl/pgsql > looses SPI connection within the middle of some function ? No, you're misinterpreting the message. What that code likely means is that something is trying to use SPI and finding plpgsql already connected. In other words, plpgsql forgets to do a SPI_push() before calling something that might try to use SPI re-entrantly. It should be perfectly deterministic and it definitely doesn't have anything to do with the states of other sessions. But we're going to need a test case to fix it. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
