Looking at the error codes, it appears that it isn't even the Postgres JDBC driver returning that error, but the XA manager you're using, which is not a part of Postgres (nor is the JDBC driver, for that matter - that's a separate project). The errors you're quoting are from the XA manager and are about XA manager stuff. For all we know, the actual error appears to be occuring in the XA manager and not in Postgres. It's possible that the XA manager error is a result of an error that Postgres returned, but since the XA manager prints its own error message and not the original one, you'll need to uncover those error messages before we can help you with them. For all we know at this point, the error is with your XA manager, not with Postgres. If you want to be sure, grep the source of the JDBC driver for those error codes; I doubt you'll find them in there.
