1) “NOTIFY” should be eligible for prepared statements to assist in the case where untrusted values is part of the “channel” or “payload”.

I had to write some ugly stored procedures to attempt sanitising myself

2) Query batching where queries are submitted to a database together and then results are returned. If this could be done without a connection per query that would be awesome. The use case is a global truth database needing 1 write to 20 reads… If the server is in the UK and the client is in Fiji then batching the 20 reads together is a massive latency win.
