GetForeignKeyOids was showing up in CPU profiles when distributing schemas on systems with 100k+ constraints. The reason was that this function was doing a sequence scan of pg_constraint to get the foreign keys that referenced the requested table. This fixes that by finding the constraints referencing the table through pg_depend instead of pg_constraint. We're doing this indirection, because pg_constraint doesn't have an index that we can use, but pg_depend does. |
