Grant Current and Future Objects to a User (Role) in Postgres
Published: May 21, 2020 • Updated: May 3, 2021
Ran into an issue at work with one of our flyway scripts. The script was somewhere in the middle of the migration order, so it wasn’t the first or the last script to run. This was an issue since we needed to grant read-only access to a
some_user user for both current and future tables that were created. After a bit of tinkering, I came to the below solution.
-- grant read-only access to some_user if the role exists do $do$ begin if exists (select rolname from pg_catalog.pg_roles where rolname = 'some_user') then grant usage on schema some_schema to some_user; -- current objects grant select on all tables in schema some_schema to some_user; -- future objects alter default privileges in schema some_schema grant select on tables to some_user; end if; end $do$
