I think we can be a lot more aggressive moving the cuttoff for psql than for pg_dump; but that's more an argument ripping out some old psql code. > I'm hesitant to move the cutoff really far, because we do still hear from > people running really old versions, and sooner or later those people will > want to upgrade.

E.g. saying that we support 5 more versions than the actually maintained ones. The likelihood of breakages seems to increase a good bit for older versions.
