Ah, I see the problem: pg_dump's -d/-D option doesn't do quoting of
special characters properly --- in fact, the only thing it does do
is double-up single quote marks. My testing was without that option ---
without -d or -D, pg_dump uses COPY, which quotes everything properly.
This is probably why most people weren't seeing a problem.

I'll put this on my to-do list for 6.5, but in the meantime, I'd suggest
not using -d or -D... a dump script with one INSERT per table row is
horribly slow compared to COPY anyway...
