How can anything like that possibly work with any reliability whatsoever? If the signal comes in, you don't know whether it was triggered by the event Postgres expected, or the event the perl module expected, and hence there's no way to deliver it to the right signal handler (not that the code you're describing is even trying to do that). What *I'd* like is a way to prevent libperl from touching the host application's signal handlers at all. Sadly, Perl does not actually think of itself as an embedded library, and therefore thinks it owns all resources of the process and can diddle them without anybody's permission. 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
