-New installations of Evergreen will use this code when the database tables are created.
+New installations of Evergreen will use the code in the Pg folder when the database tables are created. If you are creating a new table for a brand new feature, you'll most likely need to create a new schema file, but in this case we are updating an existing table in the actor schema.

-If you are developing an upgrade script to submit to the Evergreen community, the new upgrade script you create will likely be more complicated. See other examples in the upgrade folder. The "XXXX" in the file name is a placeholder - when the core committers add it to master, they will assign it a number.
