Fair enough. I can wait indefinitely right now, because I don't have any
serious problems with the planner as-is.
I am trying to empathize with people who are desperate to force plans
sometimes. Your original proposal included hints in the client queries.
I suggested that regexes on the server can accomplish the same goal
while avoiding a serious drawback. Don't you think some kind of server
matching rule is better?
I think an idea to get the hints into the server, regardless of the
types of hints you want to use, make it more likely to be accepted.
Don't you think that's a better road to take?
