Hi,
What details do you want ?
QxOrm builds standard SQL queries and Postgresql works without problem (like many SGBD).
There is a specific case with Postgresql and id (OIDs) : this is due to
lastInsertId() method from Qt library.
You can workaround this with QxOrm Triggers or consider OID like id for all your objects...
