Second digit is a number if rows that INSERT starement put into table.
Fist number is a row id (called in postgres 'oid'), it's uniqe row identifier. If table has been created with option 'with oids' (or such option was setting in postgresql.conf file) then every row in a table has such unique identifier (that identifier is displayed after INSERT statement) if not rows didn't have oid's and INSERT displey 0.
Is is clear (it may not because of my english :) )?
