Does anyone know how I can install libpq-dev on Mac OS 10.6? It's a pre-requisite for something else I want to install.

There doesn't seem to be a macport for it, so how can I install it on a Mac?

Consider using Homebrew

brew install postgresql

It'll give you the necessary headers.

    I don't want to install Postgresql on my Mac! I have Postgres already running in a Docker container. Just want to make this dam pg gem running. Any way to install only some kind of pg-dev header packages? Aug 19, 2015 at 9:07

    Well one thing to consider is just cause you install pg via homebrew, it doesn't mean you have to run the deamon (server). Just use the client that way, I doubt it takes up much space anyways. Aug 19, 2015 at 16:55

    It does take up significant space: brew requires 1Gb of its own git repo in order to function at all. Jun 30 at 8:51

You can install libpq (dev files are included) alone using homebrew.

brew install libpq

The include files and libs are then available in the following folders:


When I've search in ports I've found this:

port search libpq
libpqxx @3.0.2 (databases, devel)
    Official C++ client API for PostgreSQL

libpqxx26 @2.6.9 (databases, devel)
    Official C++ client API for PostgreSQL

You can try one of those.

    libpq is C connector library while libpqxx is C++. In other words - this most definitely will not help. Apr 10, 2015 at 12:31

Using macports, this worked for me:

sudo port install postgresql96
sudo port select --set postgresql postgresql96

I believe this installs all the postgres client tools and libs, while macports has a separate port for installing the server, i.e. postgresql96-server.
