I am sure there is momentary thrill of achieving minimalism but alas the world is not so simple anymore. I would refer the OP and the community here to the paper from the creator of PostgreSQL: http://cs.brown.edu/~ugur/fits_all.pdf

I think that paper is making an argument orthogonal to OP. OP is saying Postgres is a good enough solution, that the advantages of simplifying the stack outweigh the disadvantages of using a non-optimal database for basic use cases.

As is so often the case in this industry an idea comes, goes, and comes back around again. Time to reevaluate.
