The reason they're "advisory" is that the current set of functions for
accessing them doesn't enforce anything. That doesn't make the locks
themselves any more or less user-defined than they were before ---
certainly the pg_locks view has got nothing to do with whether they are
advisory or enforced. I do not see a good reason to change it.
It might be worth mentioning in the description of the pg_xxx_lock
functions that the locks they acquire are shown as "userlock" in
pg_locks, but that seems sufficient.
