Or you could use a symlink, like the solution for pg_xlog, but I don't see any advantage there.Symlinking pg_log is not ideal because the logs end up in the backup. It gets pretty weird when those logs get restored to a standby and somebody starts reading them.log_directory in postgresql.conf san be set up with an absolute directory value. So there is no actual need for a symlink with pg_log. This also reduces the amount of data transfered as part of base backups without actually needing them.Yes, I really should have said having pg_log in the data directory at all is not ideal, symlinked or no. Is there a Best Practices wiki? (https://wiki.postgresql.org/wiki/Detailed_installation_guides is pretty old and thin.) --
