okay. is there a way to have a function defined to accept an
inherited record type, that'll work in an inheritee-record?
create table basic (
v1 int4,
v2 int4
);
create table dat (
who varchar(30),
id serial
) inherits (basic);
create function calc(basic) returns int4 as '
select $1.v1 + $1.v2
' language 'sql';
...
select calc(dat);
select calc(basic*);
is there a way?
