Postgresql doesn't have support for merge at this time as an SQL
command.  However, I've seen some functions developed to simulate
this: http://www.postgresql.org/docs/current/static/plpgsql-control-structures.html#PLPGSQL-UPSERT-EXAMPLE

Regarding the second point, the manual show the capabilities of the
JDBC driver and postgresql:
