Обсуждение: table inheritance and privileges

I'm dynamically creating tables that inherit from another table but
they don't inherit the access privileges. Is there a way to have the
new tables inherit their parent tables access privileges?

No, but do you need that?  When accessing the parent table, there's
no need for privileges on individual children --- we only check
tables(s) directly named in the query.

I have written a 'before insert' trigger using a similar technique to
that described in section 5.11.3 of :
https://www.postgresql.org/docs/14/ddl-partitioning.html#DDL-PARTITIONING-USING-INHERITANCE

However my trigger queries to see if the partition table exists,
creates it if it doesn't then inserts into it and returns 'SKIP'
(plpython3u).
