Postgres is the absolute best you will get for diverse relational data with strict consistency needs and not a huge amount of data of each type (AKA, what databases were created for).

It's second best (or third) for the stuff that historically made people abandon relational databases. But it's absolutely the best choice for its core functionality.

(But well, Python is the best system scripting language around. So the phrase was always an exaggeration.)
