What are the causes of a segmentation fault in Python?

Question

PostgreSQL

So, in one place, I have about 250K objects created using bulk_create , when this method is executed, a segmentation fault crashes. I thought the pack was too big. I set batch_size to 50K, because I know for sure that 43K pass freely, but it wasn’t there, the result is the same seg fault. The question is, what could be the problem? Perhaps in the PostgreSQL configs?
