Then a name migration could work like this:

I was hoping there was some way to "add a name" to a table or column, so that old_name and new_name will both work, and then at a later time remove the old name. If existing clients are using the old name, you can't just yank it out from under them. PostgreSQL lets you rename tables and columns via alter table, but often this isn't feasible in a production without significant downtime. Sometimes one name is used in developing a feature, but testing with real users reveals that a better name is needed, and it'd be nice to have the names for things in the DB match the names used in the UI. Maybe requirements shifted slightly, or maybe as time went on, a better understanding of the concept being represented developed.
