true, if I remember well, there is substitution from anyelement to int? maybe from this perspective can be good to separate polymorphic types to some kinds: any - really unknown type - there is possible only check on null or not null (and maybe some basic operations). anytext - any value (substituted to text) in validation time anynumeric - any value (substitued to integer) in validation time. regards Pavel Stehule > > regards, tom lane > -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
