Hello Jelte,

I reviewed your patch. Overall it looks good, I didn't find any problems
with code. Documentation is in place and clear.

Initial Run
===========
The patch applies cleanly to HEAD (196063d6761). All tests successfully
pass.

Comments
===========
1) I noticed that pg_dump changes weren't covered with tests.

2) I assume these error messages may be confusing, especially first one:

> -- Fails for an already existing schema to be provided
> CREATE EXTENSION test_ext_owned_schema SCHEMA test_ext_owned_schema;
> ERROR:  schema "test_ext_owned_schema" already exists
> -- Fails because a different schema is set in control file
> CREATE EXTENSION test_ext_owned_schema SCHEMA test_schema;
> ERROR:  extension "test_ext_owned_schema" must be installed in schema
> "test_ext_owned_schema"


In both cases it's not clear that the extension requires schema ownership.
Can hint messages be added there?
