The pre-create use case would look  like:
 SELECT * FROM describe_collation(locale_string text, collprovider "char")

Post-creation, one could do:
 SELECT * FROM describe_collation(collcollate, collprovider)
   FROM pg_catalog.pg_collation WHERE oid = :OID;

Possibly it could exists as SELECT * FROM describe_collation(oid)
but that's essentially the same function.
Or I'm missing something about why we'd need two functions.
