Is it possible multiple connections per one transaction in Postgres? Golang usage

Question

I need to populate table in Postgres concurrently by using multiple connections but in scope of single transaction. Is it possible?

I don't see any way to avoid this bottleneck.

Thanks

Answer 1

I am confident that the transaction did not need to.

But if much want to - you can make a staging table, fill it with several routines, and then in a transaction to transfer data in bulk by using such "insert from select"
