RE: How to combine multiple field primary key and Row Versioning

Hello,
I suspect that it doesn't have the xid=int4 operator. Try adding the
following:

create function int4eq(xid,int4)
returns bool
as ''
language 'internal';

create operator = (
leftarg=xid,
rightarg=int4,
procedure=int4eq,
commutator='=',
negator='<>',
restrict=eqsel,
join=eqjoinsel
);

I'm assuming the server reported an error something like:
ERROR: Unable to identify an operator '=' for types 'xid' and 'int4'
You will have to retype this query using an explicit cast
Hope this helps,
- Stuart
