III. Using Row Versioning feature and creating the missing equals operator
In order to use row versioning, you must overload the int4eq function for use
with the xid type. Also, you need to create an operator to compare xid to int4.
You must do this for each database you want to use this feature on.
Here are the details:
create function int4eq(xid,int4)
returns bool
as ''
language 'internal';
create operator = (
leftarg=xid,
rightarg=int4,
procedure=int4eq,
commutator='=',
negator='<>',
restrict=eqsel,
join=eqjoinsel
);
