FWIW, I am quite afraid of #5, mainly because we are *still*
discussing fixes that will require parsetree and/or catalog changes
and thus catversion bumps. (There are two such threads on the
open-items list, and possibly more that I've not noticed.) At this
point I'd be willing to bet dinner that if we ship it in v19 there
will be post-release bug discoveries that are unfixable until v20.
