Pass table type information to the diff

[jorgecarleitao]

Postgres has table types .relkind in pg_tables that are necessary to identify whether the difference is in a table or in the partitions (as the query lists all tables and partitions).

To be able to ignore differences on partitions, it would be useful to be able to see which table type each table on each side is made of.

Suggestion: have the diff contain table types
