Seems I spoke too soon.. I just created a brand new empty database and 
added postgis by extension.
It worked correctly.

The previous database was also new but I imported a lot of data that 
came from an earlier postgis database. Seems I accidently copied some 
postgis functions somewhere because "select * from pg_proc where proname 
= 'st_asgeojson';" returned 11 rows (!).

Thanks for your input!

P.S. Do I understand correctly that CREATE EXTENSION is not a preferred 
method for postgis?
