when I use 3 similar programs to feed data, which means about 75
events every second, I found that Postgres didn't send NOTIFY
opportunely, since the client do SELECT query every several hundreds
seconds, which is too long to be acceptable.
Hello Gavin,
The following might help from the notify docs:
"NOTIFY behaves like Unix signals in one important respect: if the same
notification name is signaled multiple times in quick succession,
recipients might get only one notification event for several executions
of NOTIFY."
So if your notify for instance could also add a unique number to the
notification name, then it will probably work as expected.
