You can do something like given below:
CREATE TABLE temp_generate_inserts AS SELECT * FROM table id=xx
Then use pg_dump --column-inserts -t temp_generate_inserts db1|psql db2
and later you can drop temp_generate_inserts table.
With this you can also explore dblink_build_sql_insert function which comes with dblink module:
