Closes #127
This PR implements native schema inference for PostgreSQL using a combination of postgres native system tables and
information_schema. It handles all primitive types, array types, complex types and enums. It also handles quite a few types that the row conversion itself doesn't support yet - but those can be added over time (i.e.TSVECTOR,INET,CIDR,MACADDR,UUID,JSON,JSONB,XML).This allows the schema to be retrieved even for tables without any rows.
