According to the documentation –inserts option is mainly useful for making dumps that can be loaded into non-PostgreSQL databases and to reduce the amount of rows that might lost during error in reloading but multi values insert command are equally portable and compact and also faster to reload than single row statement. I think it deserve an option of its own
The patch attached add additional option for multi values insert statement with a default values of 100 row per statement so the row lose during error is at most 100 rather than entire table.
