When we need to do a schema change, write a sql file that produces the changes we want.
Put that in an updates directory, prefixed with the date. e.g. 20201005-drop-all-tables.sql
Spin up a test database with the current schema.sql loaded in, and run the update file against it.
Dump that database schema back into schema.sql.
Notes
Current master schema.sql is based off legacy/usgo-agagd-scheme-no-zero-dates-20200913.sql. The prod will continue to use zero dates which will be removed later.
