## Description 

Add a compatibility check on server start `server.run` that goes through
each table in the schema and makes a simple `select * from table limit
1`

I've added `Selectable` as a macro to the Rust structs that correspond
to the data we'd select from each table, so we can use it in the macro

## Test plan 

How did you test the new or updated feature?
