@Pl45m4 But since we don't have a sql-driver for this database the only way is to either use the c++ api from this database directly or write a new sql plugin.

I have said nothing else ;-)

But I'm wondering if the QPSQL driver will work

Yes, I am trying to connect questDB with complied postgrespl driver, since questDB says it supports PostgreSQL wire protocol in https://questdb.io/docs/develop/query-data/.
Till now, I still don't make it with complied postgrespl driver.
I have no idea that complied postgrespl driver is the same as complied postgrespl driver in QT?
Thanks a lots!

Qt does not compile any postgresql driver. It just creates a Qt plugin which is using the postgresql libs to connect to a psql database. If this does not work then you have to ask the questDB people what's wrong since the plugin works very well with a psql server.

Thanks, I've made it with postgrespl native header file. It's ok to access questDB right now.
