size of pg_dump files containing bytea values

I notice that non-printables in bytea values are being spit out by pg_dump
using escaped octet sequences even when the "-Fc" option is present
specifying use of the custom binary output format rather than plain text
format. This bloats the size of bytea values in the dump file by a factor
of 3+ typically. When you have alot of large bytea values in your db this
can add up very quickly.

Shouldn't the custom format be smart and just write the raw bytes to the
output file rather than trying to make them ascii readable?

Thanks.
