 ## Schema Updates
 
 Once a table is partitioned, here’s how to change the schema:
 
 - To add, remove, or modify a column, make the update on the master table only
-- To add or remove an index, make the update on the master table and all partitions
+- To add or remove an index, make the update on the master table and all partitions (for Postgres 11, make the update on the master table only)
 
 ## Declarative Partitioning
 
 Postgres 10 introduces [declarative partitioning](https://www.postgresql.org/docs/10/static/ddl-partitioning.html#ddl-partitioning-declarative). A major benefit is `INSERT` statements with a `RETURNING` clause work as expected. If you prefer to use trigger-based partitioning instead (not recommended), pass the `--trigger-based` option to the `prep` command.
