Goodbye MongoDB, Hello PostgreSQL (2015)

I've never seen an article about switching from Postgres to something else. Obviously Citus, Timescale, and other Postgres forks don't count.

Uber did one a while ago, but tl;dr they didn't really understand Postgres very well and were dealing with unique problems.

I have seen Uber ping-ponging between Postgres and MySQL. My approach to this problem is, can we use Postgres? If the answer is yes (90% of the cases) we use Postgres. If the answer if no investigate what is good out there. For k:v I have used Riak with much satisfaction. For distributed databases we are experimenting with TiDB. It looks very promising so far.

There is only one problem with Postgres that I run into. Client connection scalability. This is why many users use a connection proxy in the front of it.

I'm not sure they understood the problem they were trying to solve let alone understood Postgres.
