DM-38831: Initial DP0.3 schema

[ctslater]

Only reflects preliminary data file schema with no modifications.

• No mpcorb table?
• Postgres tables as ingested are all lower-case (both table names and columns names; Postgres by default coerces all names to lowercase unless quoted.) If TAP quotes these mixed-case table and column names, I don't believe they will match...
• Should we strip myqsql: attributes?

Thanks, all good points. I just pushed an MPCORB table. I don't think we need to do anything about the mysql attributes; felis will use those if you ask it to generate mysql DDL, but should ignore them otherwise.

The capitalization issue is pretty tricky. I'm kind of reluctant to convert these mostly-camelcase names all to lowercase. My memory is also that TAP quotes all identifiers.

[capitalization] I guess we can try and see? If everything ends up quoted, we'll have to rename everything already in Postgres to camelcase (ALTER TABLE; not particularly hard).
