The scenario I was imagining was: 1. perl temporarily takes over SIGALRM. 2. while perl function is running, statement_timeout expires, causing SIGALRM to be delivered. 3. perl code is probably totally confused, and even if it isn't, statement_timeout will not be enforced since Postgres won't ever get the interrupt. Even if you don't think statement_timeout is a particularly critical piece of functionality, similar interference with the delivery of, say, SIGUSR1 would be catastrophic. How do you propose to prevent this sort of problem? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
