Agreed, extensions really should never be in a path searched by the dynamic linker, even if the prefix contains 'postgres'. To me that's a separate thing from adding postgresql to datadir, sysconfdir, includedir, docdir... On a green field I'd say the 'extension library' directory should just always be extensions/ or such. Greetings, Andres Freund
