Re: plpgsql trigger coredumps instance

There is no solid test scenario, as it doesn't happen every time,
and I couldn't reproduce it by manually running the queries.

Not the entire thing was compiled with debugging symbols, here is
what I get for stack trace:

the system is FreeBSD 6.2 AMD64 running on Xeon 64 bit.
