You have to do both things, first compile with WAL_DEBUG, and then set the wal_debug guc to on. One question: Do i need to uninstall first before I gmake install again? > I've never bothered to do that and it never gave me any problems (but I wouldn't so on a running production system). You do need to run make maintainer-clean before you redo the ./config and build and install, though. > If so, any idean how to uninstall it? > If you originally installed from source yourself using the normal build tools, uninstalling should need nothing more than removing the directory that --prefix was originally set to. If you had built other things that linked against the installation (DBD::Pg, for example) they will be broken by this, but they should work again once you redo the install. If you installed some other way, I don't know. Cheers, Jeff
