That was discussed in the scope of the first extension patch and it took
us about 1 year to conclude not to try to solve search_path at the same
time as extensions. I'm not convinced we've had extensions for long
enough to be able to reach a conclusion already, but I'll friendly watch
that conversation happen again.

My opinion is that a pg_extension schema with a proper and well
documented set of search_path properties would be good to have. A way to
rename it per-database doesn't strike me as that useful as long as we
have ALTER EXTENSION … SET SCHEMA …

The current default schema where to install extensions being "public",
almost anything we do on that front will be an improvement.
