When calling functions, it seems like I need to prefix with message_store., otherwise I get an error saying the function does not exist.

Though, even when executing a function with the prefix, it fails since the body of the function itself calls another function but doesn't include the schema prefix.

SELECT * FROM message_store.get_stream_messages('someStream-123', 0, 1000, condition => 'messages.time::time >= current_time');

ERROR:  function is_category(character varying) does not exist
LINE 1: is_category(get_stream_messages.stream_name)
        ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.
QUERY:  is_category(get_stream_messages.stream_name)
CONTEXT:  PL/pgSQL function message_store.get_stream_messages(character varying,bigint,bigint,character varying) line 6 at IF
SQL state: 42883

I believe the is_category function should be message_store.is_category in this snippet:
https://github.com/message-db/message-db/blob/master/database/functions/get-stream-messages.sql#L13

Its possible this prefix might need to be added to other functions, I just haven't done much testing.

Also, is there any reason why I'm forced to use the schema prefix? It seems like other people don't have this problem?
