How to install driver for postgresql

[Arnt]

Hello,

I run Python 2.7.12 |Anaconda 4.1.1 (64-bit) on Windows 7.

I want to read from a PostgreSQL database and needs the driver 

PostgreSQL -vector- (rw+): PostgreSQL/PostGIS

But how do I make that available for my Anaconda python?

I have run > conda install postgresql 

which installed postgresql   9.5.4  vc9_2  [vc9]  conda-forge

But still the driver is not listed as available: 

for i in range(0,ogr.GetDriverCount()):

    if 'SQL' in ogr.GetDriver(i).name:

        print ogr.GetDriver(i).name

only lists

SQLite

MSSQLSpatial

What else do I need to do in order for it to work?  

Best regards,

Arnt
