we are migrating a powerbuilder 2019 project from Oracle to Postgres 12.
The async database parameter is set to 1 and the retrieverow event is coded, so i can cancel a retrieve.
When i am connected to Oracle (native driver), everything works fine.
With postgres (psqlODBC driver) i can't cancel the retrieve.
A cancel is only possible when the database returns rows (not before).
Is this a known issue?
