Hello.

I've found this on the docs:
https://www.postgresql.org/docs/devel/static/plpgsql-control-structures.html#PLPGSQL-STATEMENTS-RETURNING-PROCEDURE
> If a RETURN statement is desired to exit the code early, then NULL must
be returned.

But isn't actual syntax just RETURN without an expression?
