Hi Hackers, I’m submitting a patch as part of the broader Retail DDL Functions project described by Andrew Dunstan https://www.postgresql.org/message-id/945db7c5-be75-45bf-b55b-cb1e56f2e3e9%40dunslane.net
This patch adds a new system function pg_get_policy_ddl(table, policy_name,
pretty), which reconstructs the CREATE POLICY statement for a given table
and policy. When the pretty flag is set to true, the function returns a
neatly formatted, multi-line DDL statement instead of a single-line
statement.
Usage examples:
1) SELECT pg_get_policy_ddl('rls_tbl_1', 'rls_p8', false); -- *non-pretty
formatted DDL*
pg_get_policy_ddl
---------------------------------------------------------------------------------------------------------------------------------------------------------------
CREATE POLICY rls_p8 ON rls_tbl_1 AS PERMISSIVE FOR ALL TO
regress_rls_alice, regress_rls_dave USING (true);
2) SELECT pg_get_policy_ddl('rls_tbl_1', 'rls_p8', true); -- *pretty
formatted DDL*
pg_get_policy_ddl
------------------------------------------------
CREATE POLICY rls_p8 ON rls_tbl_1
AS PERMISSIVE
FOR ALL
TO regress_rls_alice, regress_rls_dave
USING (true)
;
The patch includes documentation, in-code comments, and regression tests,
all of which pass successfully.
