ctrl \ makes psql 8.2.5 dump core

On OS X (10.4.11) with Postgres 8.2.4, control-\ in psql just quits
(drops back to shell prompt).

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.

Welcome to psql 8.2.5, the PostgreSQL interactive terminal.

\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,

This is normal and expected. Ctrl-\ is SIGABRT. If somewhere it aborts
without dumping core, it's because you have a zero "core size" ulimit
setting.

I believe this is expected behavior the Ctrl-\ keystroke will cause a SIGQUIT to the current process. Any program that doesn't explicitly handle SIGQUIT will abort.
