I don't think anything's being "trimmed out". It's the normal behavior
of regclass literals to not print the schema if the table (or sequence
in this case) is visible in the current search_path.

This claim is utter nonsense. If you are having a problem it's not due
to the way regclass literals print. Please show a complete example of
something failing.
