Well, more specifically, it's created under the OS user & group that
the server is running under.

What current user?  The SQL user name might not correspond to any
OS-level entity at all.  Even if it did, it's quite unlikely that
the OS would permit the server process to create files owned by
some other OS user --- doing so would be a giant security risk.

You can set up the log files as readable by the OS group of the server
(see log_file_mode), and then grant membership in that group to whichever
OS accounts you trust.  You may also need to move the log directory
out from under $PGDATA to make that work, since PG doesn't like
world-readable data directories.
