(Yes, we know it's old, we're moving to 6.7, but we still have some older servers to support and we want to run the same Pg on the new and the old. :) I used pg_upgrade, but the details don't matter now... -----Original Message----- From: Tom Lane [mailto:tgl@xxxxxxxxxxxxx] > The postmaster is evidently deciding that /home/postgres is supposed to be the data directory. The only theory I can think of to explain this is that /nms-db/9.5/data contains a postgresql.conf file that sets data_directory in a way that resolves as that. It is definitely finding a postgresql.conf somewhere, else you'd not have gotten this far. > Possibly you have "data_directory = ." or something like that in the config file? Wow, you nailed it! For some reason, I read over: data_directory = '' # that's 2 single quotes and therefore the empty string multiple times and missed it every time. I set that to the proper dir and life is good again. Obviously, that's something that must be changed in the automated upgrade script. While it might be nice if the server warned of an "empty" dir for that config value, the problem was totally mine.
