I added a "NOFITY chan" to the SQL arg of an SPI_execute(), (I did it also with just the NOTIFY statement), but the listeners (other workers) don't get the notification until a "NOTIFY chan" is done for example with pgadmin,
They don't get lost, just not emited after the "not forgotten" call of CommitTransactionCommand().
Is this normal ( i.e. not supported (yet) ), a bug, or did I overlook some doc. (or source code) ?.
For now, I will try to "emit" the NOTIFY via libpq.
That's because ProcessCompletedNotifies isn't being called. For regular backends it is called inside the top level loop PostgresMain. I think you need to include "commands/async.h" and add a call to ProcessCompletedNotifies() after your background worker commits to make this work.
