Psycopg2 in a VirtualEnv
July 21, 2011
I tried to install psycopg2 in a VirtualEnv on debian, and got the following:

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'.
error: Setup script exited with 1
This is fixable by installing a couple more packages in debian:
# apt-get install libpq-dev python-dev
Once this is done, we can install the python postgres driver:
