Re: Re: proposal: make NOTIFY list de-duplication optional

Thank you.

Here is my latest attempt, with actual syntax error handling.

Also, the syntax is updated to what Tom Lane suggested in other
thread (with another variant of the same thing, from Julien Demoor)
NOTIFY [ ( option [, ...] ) ] channel [ , payload ]

Still no hash table fallback is implemented, so this is *not* a
performance improvement. Only a little more flexibility.
