Which is a very good argument for multiarch.

Currently you would have to install a complete mips64 system to get a
64bit postgresql. That makes the system much bigger and slower

With multiarch you can install a mips system and then install only the
postgreql from mips64 (+ essentials and depends).

With the exception of amd64 the suggested multiarch ports for sparc64,
s390x, mips64, mipsel64, powerpc64 are not ment to encompass the full
16K packages debian has but just the essentials and a selected
handfull of packages like postgresql that require the 64bit address
space for some users.
