This error is because by default the debian package manager is trying to
download details on all supported architectures, but failing to find one
for i386. You can add an architecture tag to the repository definition
in the source list file i.e. /etc/apt/sources.list or
/etc/apt/sources.list.d/postgres.list (or whatever you have called
itIf). Try adding the arch option as

deb [ arch=amd64 ] http://.....
deb-src [arch=amd64 ] ...

This should tell apt to only look for the amd64 packages.
