How do I use the row versioning -OR- why do I get a message about no operator for xid and int4?
Some of the operators are missing in some releases of PostgreSQL (anyone remember which?) so 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. This will probably not be necessary in PostgreSQL 6.4 since it will be added.
