Make plpgsql_trap test more robust and less resource-intensive. We were using "select count(*) into x from generate_series(1, 1_000_000_000_000)" to waste one second waiting for a statement timeout trap. Aside from consuming CPU to little purpose, this could easily eat several hundred MB of temporary file space, which has been observed to cause out-of-disk-space errors in the buildfarm. Let's just use "pg_sleep(10)", which is far less resource-intensive.
Also update the "when others" exception handler so that if it does ever again trap an error, it will tell us what error. The cause of these intermittent buildfarm failures had been obscure for awhile.
