Can you get a core dump and/or a stack trace out of it? I noted that
you're running Gentoo, so recompiling with --enable-debug, if it's not
compiled with it already, shouldn't be a problem :). --enable-cassert
could be helpful as well, though that does have an impact on performace.

Let me know if you need help compiling or getting a core dump or stack
trace with gdb.

Not really. If the query that crashed works when ran after restart, it's
not likely that corruption caused the crash. You could take a backup
with pg_dump; that at least scans through all data, so if something is
corrupted in a table it will complain.
