Puzzling:

drop table foo;

create table foo (a int unique not null, b text);

drop function foo_ins();

create function foo_ins() returns int as '
declare
  va int;
  vb text;
begin
  va := 1;
  vb := ''xxxxx'';
  INSERT INTO foo (a,b) VALUES (va,vb);
  return 1;
end;
' language 'plpgsql';

select foo_ins();
 foo_ins
---------
       1
(1 row)

select * from foo;
 a |   b
---+-------
 1 | xxxxx
(1 row)


Works fine here - v7.1.1 but I'm sure I'd have noticed problems in previous
versions if there'd been a fault. I'd suspect some issue with the type of
the variable or something.

What precisely is the error and is it possible to provide the table and
function definition?
