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.... Using --force. I assume you know what you are doing...
