Re: new and old as parameter in a function

You misread it --- that's not presently supported.

regression=# create function foo(record) returns int as '
regression'# begin
regression'#   return $1.f1;
regression'# end' language plpgsql;
ERROR:  plpgsql functions cannot take type record

However you can make a plpgsql function that accepts a parameter of a
specific (named) rowtype:

regression=# create table fooey(f1 int, f2 text);
CREATE TABLE
regression=# create function foo(fooey) returns int as '
regression'# begin
regression'#   return $1.f1;
regression'# end' language plpgsql;
CREATE FUNCTION
