Any native libraries for ZeroMQ, MySQL, PostgreSQL?

 
Are there any MQL5 native libraries for ZeroMQ, MySQL, PostgreSQL?
 
Nope! Unfortunately! Just for SQLite, since February, 2020. And it is absolutely necessary a real multiuser database for MQL5, like PostgreSQL. It would transform completely the trading robots architecture, a new and far more effective way of thinking them. It is uncompreensible why @MetaQuotes Support doesn't implement it yet!
