DROP POLICY
DROP POLICY — remove a row level security policy from a table
Synopsis
DROP POLICY [ IF EXISTS ] name ON table_name [ CASCADE | RESTRICT ]
Description
DROP POLICY removes the specified policy from the table. Note that if the last policy is removed for a table and the table still has row level security enabled via ALTER TABLE, then the default-deny policy will be used. ALTER TABLE ... DISABLE ROW LEVEL SECURITY can be used to disable row level security for a table, whether policies for the table exist or not.
Parameters
- IF EXISTS
-  Do not throw an error if the policy does not exist. A notice is issued in this case. 
- name
-  The name of the policy to drop. 
- table_name
-  The name (optionally schema-qualified) of the table that the policy is on. 
- 
CASCADERESTRICT
-  These key words do not have any effect, since there are no dependencies on policies. 
Examples
To drop the policy called p1 on the table named my_table:
DROP POLICY p1 ON my_table;
