> We are developing a tool called sqlfuzz for automatically finding performance regressions in PostgreSQL. sqlfuzz performs mutational fuzzing to generate SQL queries that take more time to execute on the latest version of PostgreSQL compared to prior versions. We hope that these queries would help further increase the utility of the regression test suite.
Hi,
is sqlfuzz available anywhere? Does it have anything to do with
sqlsmith? The query formatting looks very much like sqlsmith's.
Christoph
