54.38. pg_policy
#
The catalog pg_policy
stores row-level security policies for tables. A policy includes the kind of command that it applies to (possibly all commands), the roles that it applies to, the expression to be added as a security-barrier qualification to queries that include the table, and the expression to be added as a WITH CHECK
option for queries that attempt to add new records to the table.
