I'm trying to send a notification from the PG extension directly.
It turns out the mechanism that is used in the async file. (Async_Notify) does not suit me since the function uses oldcontext = MemoryContextSwitchTo (CurTransactionContext); and MemoryContextSwitchTo (oldcontext);
And I did not find the ability to add notification except the Async_Notify function.
Now only SPI_execute works ("NOTIFY chanel,’message’", false, 0);
P.S. In my extension, there is already a higher function started with oldcontext = MemoryContextSwitchTo (CurTransactionContext); and MemoryContextSwitchTo (oldcontext);

>>Hello! I wrote my extension for PG and am trying to run Async_Notify from it. But messages come very late! Sometimes only after I execute the notify command from the shell. What am I doing wrong? How to use Async_Notify correctly.
