Please keep doing that testing.
The SQLite people have been using a tool like this for some time. They've also had luck finding bugs with a generic fuzz-testing tool called "american fuzzy lop" (yes, seriously, that's what it's called), which apparently is the state of the art. I myself ran that tool against Postgres. I didn't spend enough time to tweak it in a way that might have been effective. I also didn't figure out a way to make iterations fast enough for the tool to be effective, because I was invoking Postgres in single-user mode. I might pick it up again in the future, but probably for a more targeted case. -- 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
