When looking at the report in [0] an API choice in the relevant pg_upgrade code path stood out as curious. check_is_install_user() runs this query to ensure that only the install user is present in the cluster:
res = executeQueryOrDie(conn, "SELECT COUNT(*) " "FROM pg_catalog.pg_roles " "WHERE rolname !~ '^pg_'"); The result is then verified with the following: if (cluster == &new_cluster && atooid(PQgetvalue(res, 0, 0)) != 1) pg_fatal("Only the install user can be defined in the new cluster."); This was changed from atoi() in ee646df59 with no specific comment on why. This is not a bug, since atooid() will do the right thing here, but it threw me off reading the code and might well confuse others. Is there a reason not to change this back to atoi() for code clarity as we're not reading an Oid here? -- Daniel Gustafsson [0] ve1p191mb1118e9752d4ead45205e995cd6...@ve1p191mb1118.eurp191.prod.outlook.com
