This patch allows "PGC_SUSET" parameters to be set by non-superusers if they have been explicitly granted the privilege to do so. The privilege to perform ALTER SYSTEM SET/RESET on a specific parameter can also be granted. Such privileges are cluster-wide, not per database. They are tracked in a new shared catalog, pg_parameter_acl. Granting and revoking these new privileges works as one would expect. One caveat is that PGC_USERSET GUCs are unaffected by the SET privilege --- one could wish that those were handled by a revocable grant to PUBLIC, but they are not, because we couldn't make it robust enough for GUCs defined by extensions.
