Обсуждение: ctrl \ makes psql 8.2.5 dump core
Hi all,
I found out this morning that entering CTRL \ at the psql prompt will
make psql dump core. The is reproducible on the two machines I have
here. Another server running downtown just quits without dumping core.
All are running 8.2.5 on OpenBSD.
I thought I was in the editor, and that key combination invokes nano's
search and replace function.
jross@slony:/var/www/wykids/training-calendar $ psql --version
psql (PostgreSQL) 8.2.5
contains support for command-line editing
jross@slony:/var/www/wykids/training-calendar $ psql wykids
Welcome to psql 8.2.5, the PostgreSQL interactive terminal.
Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit
jross@wykids localhost# Quit (core dumped)
The core file is less than a meg in size, so I can either upload it to
our web site or e-mail it directly to someone if anyone is interested.
Thanks,
Jeff Ross
On OS X (10.4.11) with Postgres 8.2.4, control-\ in psql just quits (drops back to shell prompt).

If somewhere it aborts without dumping core, it's because you have a zero "core size" ulimit setting. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.
I believe this is expected behavior the Ctrl-\ keystroke will cause a SIGQUIT to the current process. Any program that
doesn'texplicitly handle SIGQUIT will abort.
