I want to connect my Django application to an Amazon RDS for PostgreSQL database.

Do I need psycopg2 installed? (I think yes)
How do I install pyscopg2 in a way that doesn't require an entire postgres db install.

The error when installing psycopg2 now is this:

Error: pg_config executable not found.

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'.

I'm on CentOS7.

I tried:

$ yum install postgresql-libs
$ yum install python-psycopg2

These packages installed, but I still get the same error on trying to pip install pyscopg2 after.

Which operating system? You need the postgresql-client development library for your platform – Antti Haapala Apr 04 '16 at 09:21
I added it to the question, CentOS7 – Michael van de Waeter Apr 04 '16 at 09:23

Solution in the duplicate target: `sudo yum install postgresql-devel` – Antti Haapala Apr 04 '16 at 09:28

and yes, psycopg2 is **the** preferred client library to connect to PostgreSQL dbs (including RDS). – Antti Haapala Apr 04 '16 at 09:31
Yes, that works. And now I don't have a postgres database running right? – Michael van de Waeter Apr 04 '16 at 09:31

well, you can check your `ps aux|grep postgres`, never too sure about CentOS – Antti Haapala Apr 04 '16 at 09:32
I checked, and no postgres was running, so I guess now the bare minimal is installed, to get psychopg2 installed. thanks! – Michael van de Waeter Apr 04 '16 at 10:13
