Hmm.  There used to be some off-by-one type bugs in psql's
variable-substitution code, but those were fixed long before 7.3.2.
In any case, it's hard to see why such a problem would only arise
when you got past 10Mb string lengths.

I couldn't duplicate the problem here, so I'm going to suggest that
maybe you have a hardware problem?  Perhaps there's a flaky RAM chip in
an area of memory that doesn't get used until you push up the size
of psql quite a bit.  It'd be worth running memtest86 for awhile to
check.
