check  Library PostgreSQL 9 3 bin and you should find pg config  I E   Library PostgreSQL  lt version num gt    ps  you can do the following if you deem it necessary for your pg needs -  create a  profile in your   directory  export PG HOME  Library PostgreSQL 9 3 export PATH  PATH  PG HOME bin   You can now use psql or postgres commands from the terminal  and install psycopg2 or any other dependency without issues  plus you can always just ls  PG HOME bin when you feel like peeking at your pg dir

You can find the pg config directory using its namesake     pg config --bindir  usr lib postgresql 9 1 bin      Tested on Mac and Debian   The only wrinkle is that I can t see how to find the bindir for different versions of postgres installed on the same machine   It s fairly easy to guess though   -   Note  I updated my pg config to 9 5 on Debian with   sudo apt-get install postgresql-server-dev-9 5

To summarize -- PostgreSQL installs its files  including its binary or executable files  in different locations  depending on the version number and the installation method    Some of the possibilities    usr local bin   Library PostgreSQL 9 2 bin   Applications Postgres93 app Contents MacOS bin   Applications Postgres app Contents Versions 9 3 bin    No wonder people get confused   Also  if your  PATH environment variable includes a path to the directory that includes an executable file  to confirm this  use echo  PATH on the command line  then you can run which pg config  which psql  etc  to find out where the file is located

Once you install the current PostgreSQL app on the MacOS X 10 11  this is where the pg config file is  Library PostgreSQL 9 5 bin pg config   Then on the Terminal         export PG HOME  Library PostgreSQL 9 5       export PATH  PATH  PG HOME bin   This will put the path in the  profile of whatever terminal you are using   In your environment  assuming you are using virtualenv  you then install psycopg2         pip install psycopg2   You should see if you had downloaded it before       Collecting psycopg2       Using cached psycopg2-2 6 1 tar gz     Installing collected packages  psycopg2       Running setup py install for psycopg2     done     Successfully installed psycopg2-2 6 1

I recommend that you try to use Postgres app   http   postgresapp com  This way you can easily turn Postgres on and off on your Mac   Once you do  add the path to Postgres to your  profile file by appending the following   PATH   Applications Postgres app Contents Versions latest bin  PATH    Only after you added Postgres to your path you can try to install psycopg2 either within a virtual environment  using pip  or into your global site packages
