@mjuric I wanted to revist this PR, as it predates there even being a base PPDB schema with the DIA tables as added in #450.

After that is merged, do you want to rebase this PR and include the Solar System tables on top of the new schema? Or would you rather I integrated the contents of this PR myself on another branch/PR?

I'm willing to do it in whatever way is most convenient for you.

Could you also let me know for reference whether or not this schema is current with the schema of the parquet data being produced by Solar System Processing? If not, what updates would we need?
