Postgres insert optimization

Question

I have a script that generates tens of thousands of inserts into a postgres db through a custom ORM. As you can imagine, it\'s quite slow. This is used for development purpose

Answer 1

Are you sending a batch of tens of thousands of INSERTs OR are you sending tens of thousands of INSERTs?

I know with Hibernate you can batch all your SQL statements up and send them at the end in one big chunk instead of taking the tax of network and database overhead of making thousands of SQL statements individually.
