Tom Lane 35af5422f6 Make the server track an 'XID epoch', that is, maintain higher-order bits ... of the transaction ID counter. Nothing is done with the epoch except to store it in checkpoint records, but this provides a foundation with which add-on code can pretend that XIDs never wrap around. This is a severely trimmed and rewritten version of the xxid patch submitted by Marko Kreen. Per discussion, the epoch counter seems the only part of xxid that really needs to be in the core server.		2006-08-21 16:16:31 +00:00
