Not worth much. MongoDB is a completely different beast after version 3.0 with WiredTiger being the default.

But I am sure that there are use cases for which PostgreSQL is going to be much faster in particular single field lookups on unindexed fields across all records.

My point is that it's never black & white to say Database A is faster than Database B. It's always use case dependent.

Point being when someone says something is faster without providing verifiable numbers... it should not really be taken seriously
