Hi,

What is the main goal?

even using libpg - you need to call pg notify... Doc says, just using libpgtcl would be possible to get Notify event - without checking from time to time...

Kind Regards,

Misa

Too bad ... Thanks for the confirmation.

I'll try to invoke a native libpg binary which stays alive until a
NOTIFY is received, should do the trick in case update-frequency is
low.

Thanks, Clemens
