ALTER POLICY — change the definition of a row level security policy

ALTER POLICY changes the definition of an existing
row-level security policy. Note that ALTER POLICY
only allows the set of roles to which the policy applies and the
USING and WITH CHECK expressions to
be modified. To change other properties of a policy, such as the command
to which it applies or whether it is permissive or restrictive, the policy
must be dropped and recreated.
To use ALTER POLICY, you must own the table that
the policy applies to.
In the second form of ALTER POLICY, the role list,
using_expression, and
check_expression are replaced
independently if specified. When one of those clauses is omitted, the
corresponding part of the policy is unchanged.
nameThe name of an existing policy to alter.
table_nameThe name (optionally schema-qualified) of the table that the policy is on.
new_nameThe new name for the policy.
role_name
The role(s) to which the policy applies. Multiple roles can be
specified at one time. To apply the policy to all roles,
use PUBLIC.
using_expression
The USING expression for the policy.
See CREATE POLICY for details.
check_expression
The WITH CHECK expression for the policy.
See CREATE POLICY for details.
ALTER POLICY is a PostgreSQL extension.
