Well, I dunno; people with a weak grasp of English might have an issue
there.  But I never liked that directory name anyway; my problem with
it is I read "pg_logical" and think "logical what?".  Naming things using
a disconnected adjective is not good, especially one with as many
potential applications as that one has.  If we're up for renaming things
under PGDATA, that one is high on my hit list.
