just created another new empty database cluster because I run out of them on my test box here at home. :-) After all,
eachdrop/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
extensiondidn'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
reallycurious about that next week. 

Thanks for the tips.

Cheers,
Paul
