将PostgreSQL客户端库更新到9.1

Question

I am installing psycopg2 using this command:

pip3 install psycopg2

But the output is:

./psycopg/psycopg.h:30:2: error: #error "Psycopg requires PostgreSQL client library (libpq) >= 9.1"

My pg_config version: pg_config --version is PostgreSQL 8.4.20 . How to upgrade PostgreSQL client library? I am searching from Google, but no method to guide me. Python version: 3.5.0.
