FWIW, that work and aggravation part is what I hoped to avoid with GUCs.
I do think that whichever route we go, we're going to be stuck
supporting the old version for a LONG time. A big part of why
standard_conforming_strings was so ugly is users didn't have enough time
to adjust. If we'd had that enabled by default for 4-5 releases it
wouldn't have been nearly as much of an issue.
