It's worth pointing out here that catversion was only intended to be useful within a development cycle, ie, to prevent developers from wasting time chasing pseudo-bugs that were really due to mismatch of their newly compiled backend executable with not-so-new system catalog contents. We never intended any code to depend on its specific value, else we'd have used a definition with more mnemonic content than a date-stamp. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
