I'm worried about that breaking things and us only noticing down the
road. This doesn't fix a problem that we are actively hitting, and as
you say it's arguably compliant to do it differently. Potential protocol
incompatibilities are a dangerous area. I think before doing something
like this we ought to at least verify that the most popular native
drivers won't have a problem with the change. Maybe pgjdbc, npgsql, the
popular go ones and rust-postgres?
