So during pg_restore, seek error was seen. Are you really using PG 9.2.something? If not, then what? The problem here probably is that pg_restore is failing to detect that the pipe input file is not seekable. We've had repeated rounds of fixes to try to detect that reliably on Windows. I think it works if you are running a current PG release (something shipped in the last six months), but maybe not with older ones. regards, tom lane
