Hi PostgreSQL developers, FYI, this was recently sent to the ancient old Debian bug report 'Postmaster ignores SIGPIPE'. [1] It seems that this was introduced way back in 1997 in [2], but withouth a sufficient explanation why SIGPIPE isn't properly handled instead of just ignored.
The bug trail in [1] contains a followup from Tom that ignoring SIGPIPE is specifically intended. Is there any document which states the reason for that? Thanks in advance for any insight, Martin [1] http://bugs.debian.org/255208 [2] http://archives.postgresql.org/pgsql-hackers/1997-02/msg00276.php ----- Forwarded message from Markus Schaber <[EMAIL PROTECTED]> ----- Subject: Bug#255208: Would help with client aborts, too. Reply-To: Markus Schaber <[EMAIL PROTECTED]>, [EMAIL PROTECTED] Date: Fri, 24 Mar 2006 13:08:55 +0100 From: Markus Schaber <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] X-Spam-Status: No, score=0.7 required=4.0 tests=AWL,BAYES_50, DATE_IN_FUTURE_06_12 autolearn=no version=3.0.3 Hello, Listening to SIGPIPE could also help detecting "unclean" client-side connection aborts, e. G. due to a program crash or sigkill on the client, or network problem between server and client. This way, the server could abort long-running statements immediately, instead of running them just to rollback them afterwards because the client does not commit. During development, I often forcedly abort my java clients, but the server continues to execute the current statement. Having two or three such sequential scans running in the background, selectively sending SIGTERM to the backends as root is the only way to get the postmaster responsive again.
