pg_seclabel — PostgreSQL system catalog

The PostgreSQL pg_seclabel system catalog: full column reference (names, types, descriptions), catalog relationships and version support.

Summary

The catalog pg_seclabel stores security labels on database objects. Security labels can be manipulated with the SECURITY LABEL command. For an easier way to view security labels, see pg_seclabels.

(Description quoted from the official PostgreSQL documentation.)

Columns

The pg_seclabel system catalog exposes the following columns (names, types and descriptions are taken verbatim from the PostgreSQL documentation):

  • objoid oid references any OID column
    The OID of the object this security label pertains to
  • classoid oid references pg_class.oid
    The OID of the system catalog this object appears in
  • objsubid int4
    For a security label on a table column, this is the column number (the objoid and classoid refer to the table itself). For all other object types, this column is zero.
  • provider text
    The label provider associated with this label.
  • label text
    The security label applied to this object.
