D'oh!  I'm blind as a bat today.

Cool, but surely the right fix is to make pg_strtof() adhere to
the POSIX specification, so we don't have to learn this lesson
again elsewhere.  I'll go make it so.

Independently of that, do we want to switch over to storing
reltuples as a string instead of converting it?  I still feel
uncomfortable about the amount of baggage we added to pg_dump
to avoid that.
