Dimitri's suggestion is a very good one - I feel it will accomplish the

We might also want to add a flag in postgresql.conf to disable this
enhancement so that we don't break existing code.

For example using the example above, these subscriptions are possible
Subscription Meaning
PRICE.> Any price for any product on any exchange
PRICE.STOCK.> Any price for a stock on any exchange
PRICE.STOCK.NASDAQ.* Any stock price on NASDAQ
PRICE.STOCK.*.IBM Any IBM stock price on any exchange
My request is to implement the same or similar feature in Postgresql.
This does seem useful and pretty easy to implement. Should we add a
TODO?
