I plugged a storage array that was initialized with ia32 and attached it to an amd64 machine. The postmaster complained at startup that such-and-such magic value was incorrect and refused to start. However it was implied on the mailing list that for certain unlucky magic values the postmaster may have started anyway and eaten the database. -jwb ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
