# Resource postgresql::grant
#
# TODO: in mysql module, the grant resource name might look like this: 'user@host/dbname';
# I think that the API for the resource type should split these up, because it's
# easier / safer to recombine them for mysql than it is to parse them for other
# databases. Also, in the mysql module, the hostname portion of that string
# affects the user's ability to connect from remote hosts. In postgres this is
# managed via pg_hba.conf; not sure if we want to try to reconcile that difference
# in the modules or not.
