DatabaseInfo class

Tracks and caches the type and name info of relations (tables, views, indexes...).

Currently it only collects and caches RelationMessage instances.

The instance may be shared between connection pool instances.

TODO: Implement active querying using pg_class like the below query: "SELECT relname FROM pg_class WHERE relkind='r' AND oid = ?", https://www.postgresql.org/docs/current/catalog-pg-class.html
