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.
