While pimping invoke-rc.d sounds like a good idea (and should be done),
I'd prefer the postrm pg_dump that is called from dbconfig-common not to
be executed with eatmydata either. Or with something else that is
preciously hidden in some LD_PRELEOAD.
My examples were init-specific, yeah. But IMHO this should apply for
everything called via maintainer scripts.
