Creating tables (relations, sorry). Selecting from tables, nothing in the log. Hm, what you describe above looks right. > I can see that alter system set pgaudit.logx = 'all'; complains about "unrecognized configuration parameter", so something is known about pgaudit. No, that means the postmaster *doesn't* have pgaudit loaded. The fact that CREATE EXTENSION worked implies that you've got the library correctly built, so I think this must boil down to the "shared_preload_libraries" setting not having taken. You could cross-check that by seeing what "SHOW shared_preload_libraries" prints. I wonder if you forgot to remove the comment marker (#) on the shared_preload_libraries line? regards, tom lane
