Error: pg_config executable not found.
pg_config is required to build psycopg2 from source. Please add the directory
containing pg_config to the $PATH or specify the full executable path with the
option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.
For further information please check the 'doc/src/install.rst' file (also at
<http://initd.org/psycopg/docs/install.html>).

왜 그럴까?
해결책:
psycopg2 관련 모듈이 업데이트 되면서 postgresql 바이너리를 찾지 못하는 문제인 것 같다.
postgresql 관련 모듈을 다시 설치하는 것으로 해결했다.
맥에서는,
$ brew install postgresql
CentOS에서는,
$ sudo yum install postgresql postgresql-devel python-devel
