All of them? PostgreSQL has kinda left everyone else in the dust in regards to JSON support.

I'm aware there is Json support in MySQL. But my point is that it's primitive when you compare feature sets of MySQL and PostgreSQL for json.

It used to be all of them, but now it is indexing which is missing from MySQL.

Has anyone used virtual columns with MySQL for a direct json-index substitute?
