David, I try then the following -

You missed quoting the part where I describe the on clauses you need to distinguish between "them" and "me"

Me: u.uid in (player...) and (s.uid = u.uid)
Them: u.uid in (player...) and (s.uid <> u.uid)



        SELECT
                CASE WHEN c.uid = s.uid THEN 1 ELSE 0 END,
                c.msg

        AND     s.sid    = in_sid
        AND     (c.uid = myself.uid OR NOT opponent.muted)
        
        ORDER BY c.CREATED ASC;

And get the syntax error which don't quite understand:

ERROR:  missing FROM-clause entry for table "s"
LINE 57: ...yself.uid IN (g.player1, g.player2) AND myself.uid = s.uid) 
                                                                 ^

Probably because "myself" needs "s" and vice versa?
