That should be enough, if you build from source. You might have received a binary from our server instead, which was built without that setting. Set "buildfromsource always" in macports.conf, and uninstall and reinstall postgres and all of its dependencies.
If you want to use this MacPorts prefix for other things that don't need a nonstandard deployment target and you want to be able to receive binaries of those, then I recommend you leave your main MacPorts prefix /opt/local set for the default deployment target and keep binaries enabled, and install a second copy of MacPorts somewhere else like /opt/macportsfor10.13 and set its macports.conf for the 10.13 deployment target. MacPorts isn't able to use binaries for nondefault MacPorts prefixes anyway.

MacPorts will intentionally ignore this and most other environment variables you set.
