Since you probably don't remember what you did to that poor database, some ideas: 1. DROP EXTENSION pg_stat_statements; CREATE EXTENSION pg_stat_statements; If that doesn't do the trick: 2. \c template1 DROP DATABASE postgres; CREATE DATABASE postgres TEMPLATE template0 OWNER postgres; \c postgres CREATE EXTENSION pg_stat_statements; Yours, Laurenz Albe
