James Dunkerley 2b425f8e08 Restructuring Database.Connection to allow for database specific types. (#3632) ... - Added `databases`, `database`, `set_database`. - Added `schemas`, `schema`, `set_schema`. - Added `table_types`, - Added `tables`. - Moved the vast majority of the connection work into a lower level `JDBC_Connection` object. - `Connection` represents the standard API for database connections and provides a base JDBC implementation. - `SQLite_Connection` has the `Connection` API but with custom `databases` and `schemas` methods for SQLite. - `Postgres_Connection` has the `Connection` API but with custom `set_database`, `databases`, `set_schema` and `schemas` methods for Postgres. - Updated `Redshift` - no public API change.		2022-09-07 17:32:28 +00:00
