Ok, it's a hint right? Step 1 is to merge the fuzzystrmatch contrib
module into main line code. Step 2 is to use that code to determine a
close match.
CREATE FUNCTION .... LANGUAGE 'plgsql';
System notices the error, and looks for languages in pg_language that
have similar names to 'plgsql', finds 'plpgsql'.
ERROR: Language 'plgsql' not found
HINT: Perhaps you intended to use the language 'plpgsql?
Lots of work (both to implement and maintain) but it would be a neat
trick.
