Обсуждение: Can't use "any" with SQL functions

Is there a reason we disallow using "any" with SQL functions?

decibel@phonebook.local=# create function textcoalesce("any") returns
void language sql as $$SELECT coalesce( $1::text, '<NULL>' )$$;
ERROR:  SQL functions cannot have arguments of type "any"
STATEMENT:  create function textcoalesce("any") returns void language
sql as $$SELECT coalesce( $1::text, '<NULL>' )$$;

Yes.  Try "anyelement" instead.

BTW is there a reason the error messages say "plpgsql functions cannot
..." instead of "PL/pgSQL functions cannot ..."?

Somewhere along the line there was the idea that the messages ought to
match the "real" name of the PL language, which is plpgsql.  The other
name is marketing.
