When inserting rows into a postgres table, what do the numbers returned after the insert mean?

INSERT 0 100

https://www.postgresql.org/docs/9.3/sql-insert.html

On successful completion, an INSERT command returns a command tag of the form

INSERT oid count

The count is the number of rows inserted. If count is exactly one, and the target table has OIDs, then oid is the OID assigned to the inserted row. Otherwise oid is zero.
