The proposed version of pg_logdir_ls could not be called "robust" in any
way at all, considering that it fails as soon as you modify the log_filename
pattern.
I concur with Bruce that this is better left to the application side.
I don't see any basic functionality gain from doing it in the server.
The client code can look at log_filename and do the filtering just as
well (or badly) as it could possibly be done in the server. Moreover,
having a restriction like "this doesn't work unless you use this
log_filename setting" feels more reasonable on the client side than
inside the server.
