Dear List, I'm trying to migrate my MS-SQL(shit) to Postgre. My database depends on having a uniqueidentifier for all objects stored. (20 or so tables of these unique objects). In MS-SQL I can use this datatype called "uniqueidentifier" to accomplish this. What would be a similar solution in Postgre? I've looked on through the MAN pages and also scoured the net for this info...I don't necessarly need a UUID like the MS one but some unique way to identifiy each object. Thanks in advance for help /B
