You should have checked pg_extension, > or just "\dx" in psql. just created another new empty database cluster because I run out of them on my test box here at home. :-) After all, each drop/create extension seems to resolve the issue, so the cluster is unusable for repetition, unless I would restore it. Ok, I'm too lazy now... :-D Did the usual initdb -k on the new database cluster. Then the select plus your suggested \dx. Nothing there and drop extension didn't work, all as I would have expected. This is strange. I will check further next week on company databases. The ones I did it up to now are my private ones at home. I'm really curious about that next week. Thanks for the tips. Cheers, Paul
