# 48.43. `pg_shseclabel`

The catalog `pg_shseclabel` stores security labels on shared database objects. Security labels can be manipulated with the SECURITY LABEL command. For an easier way to view security labels, see Section 48.66.

See also `pg_seclabel`, which performs a similar function for security labels involving objects within a single database.

Unlike most system catalogs, `pg_shseclabel` is shared across all databases of a cluster: there is only one copy of `pg_shseclabel` per cluster, not one per database.
