Re: Crash-me of PostgreSQL

I ran it a couple months ago (roughly 7.1beta1 timeframe) and got the
attached. I had to reduce the $max_buffer_size setting to "+1000000"
to prevent the perl process (not Postgres!) from running out of memory,
so some of the query-length limits shown are artifacts of that setting.

I don't regard crash-me as an unbiased or reliable indicator, but if
you want it here it is...

regards, tom lane

Running ./crash-me 1.54 on 'PostgreSQL version ???'

I hope you didn't have anything important running on this server....
