When applying the patch, I got a number of errors and the tests failed. I think it stems from:
+ targetTable = relation_open(tableID, NoLock);
+ relation_close(targetTable, NoLock);
I changed them to use "AccessShareLock" and it worked, and it's probably relevant to change table_close to "AccessShareLock" as well. You're just reading from the table.
+ table_close(pgPolicyRel, RowExclusiveLock);
You might move "Datum valueDatum" to the top of the function. The compiler screamed at me for that, so I went ahead and made that change and the screaming stopped.
+ /* Check if the policy has a TO list */
+ Datum valueDatum = heap_getattr(tuplePolicy,
I also don't think you need the extra parenthesis around "USING (%s)" and ""WITH CHECK (%s)" in the code; it seems to print it just fine without them. Other people might have different opinions.
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) ;
As for the "pretty" part. In my opinion, I don't think it's necessary, and putting the statement terminator (;) seems strange.
However, I think you're going to get a lot of opinions on what well-formatted SQL looks like.
