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.

Column Name Type References Description
polname name The name of the policy
polerelid oid pg_class.oid The table to which the policy applies
polcmd char The command type to which the policy is applied: r for SELECT, a for INSERT, w for UPDATE, d for DELETE, or * for all
polpermissive boolean   Is the policy permissive or restrictive?
polroles oid[] pg_authid.oid  The roles to which the policy is applied
polqual pg_node_tree   The expression tree to be added to the security barrier qualifications for queries that use the table
polwithcheck pg_node_tree   The expression tree to be added to the WITH CHECK qualifications for queries that attempt to add rows to the table

Note LightDB-A Database applies policies stored in pg_policy only when pg_class.relrowsecurity is set for their table.
