I simply ran the standard regression tests, and then straced a backend as it executed the pgss-calling query. I'm not sure that I've understood your question. As previously noted, my approach to testing this patch involved variations of: running "make installcheck-parallel" Concurrently, running pgbench with multiple clients each calling pg_stat_statements() and pg_stat_statements_reset(). The latter was sometimes rigged to do a direct garbage collection to stress test things. My expectation was that the sanity checking done everywhere would complain if there were any race conditions or other bugs. This was pretty effective as a smoke test during development. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
