Note this substitution sends a "pg_is_in_recovery()" query to the server

That seems kinda painful.

And what happens in an aborted transaction?

Yeah. I think we need some from help backend for this. For example, a
parameter status message can be used here.  If PostgreSQL moves to the
recovery state or vice versa, PostgreSQL sends the parameter status
message to frontend.

I agree a backend status message is the right way to do this.

We could perhaps report transaction_read_only, if we don't want to add a
new one.

I'm setting this CF item to returned with feedback, since it would
apparently be a much bigger change than then initial patch.

Yup, agree :)

Thanks for the feedback!
