I think this would rarely work in practice. For example, during the elog->ereport transition, any module compiled against the wrong server would immediately get an "unresolved symbol: elog/ereport" before you can run your nice version check. I had thought about this issue back then because it was an extrememly common occurrence; then only thing I could think of is that you trick the dynamic loader to first reference a symbol with an obvious name like "if_you_see_this_in_an_error_message_you_have_a_version_mismatch". However, this would likely be platform dependent and maybe confuse users even more. -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
