That's not the migration path I was thinking of.
What I was thinking of was:
1. Have a setting, probably per-session. Per database works too.
2. Aside from the folder upper and folder lower, have a third option.
This is "fold upper, if fails, fold lower. If succeeds, issue a
warning". This should allow programs that rely on the folding (such as
initdb) to be debugged during the transition period.
