Thank you all for considering my feature request.
Dimitri's suggestion is a very good one - I feel it will accomplish the
goal of allowing more granularity in the Listen.
We might also want to add a flag in postgresql.conf to disable this
enhancement so that we don't break existing code.
Hi pgsql-hackers,
The LISTEN / NOTIFY feature (along with the pg_notify() function) is a
unique feature that differentiates Postgresql from nearly all other
relational database systems. With the exception of SQL Server, I know
of no other RDBMSs that allow a client to be asynchronously
