[improve](jdbc catalog) Improve the speed of writing to postgresql
databases (#23279)
reWriteBatchedInserts (boolean) Default false
This will change batch inserts from insert into foo (col1, col2, col3)
values (1, 2, 3) into insert into foo (col1, col2, col3) values (1, 2, 3), (4,
5, 6) this provides 2-3x performance improvement
