Something just possibly related:

When I install PyQt5 on Linux (Debian, Ubuntu) I need to include not 
only the package python3-pyqt5.qtsql, but additionally packages like 
libqt5sql5-psql for Postgresql, -odbc, -mysql etc. Only the -sqlite 
package is installed automatically with python3-pyqt5.qtsql, I think.

So could the copy of LGPL Qt included in the wheel miss the part 
necessary for PostgreSQL?

Greetings
Sibylle
