CREATE EXTENSION not adding extension on second SCHEMA

quote from manual:

CREATE EXTENSION loads a new extension into the current database. There
must not be an extension of the same name already loaded.

You can try to alter[1]https://www.postgresql.org/docs/14/sql-alterextension.html the extension to make it located to another schema.

It doesn’t work and isn’t documented as something that does work. I really
don’t see a need to say you cannot install the same extension multiple
times explicitly - the self-describing error seems sufficient.

The CREATE EXTENSION reference page says

"There must not be an extension of the same name already loaded."

and later

"Remember that the extension itself is not considered to be within any
schema: extensions have unqualified names that must be unique
database-wide. But objects belonging to the extension can be within
schemas."

I hardly see how we could make this any plainer.

Thank you so much guys, my mistake I didn't pay attention. I'm new
to PostgreSQL and your help is much appreciated!
