I presume that batch file was executed linearly -- no parallelism?
You're actually testing one of PostgreSQL's shortcomings.
PostgreSQL (in my experience) does much better in such comparisons with
a parallel load -- multiple connections executing varied work (short
selects, complex selects, inserts, updates, deletes).
Anyway, just a tip that you will want to test your actual load. If you
do batch work with a single thread, what you have is fine. But if you
have a website with tens or hundreds of simultaneous connections then
your non-parallel testing will not reflect that work load.
