postgresql - Where do I get libpq source?

Question

I want to write application which uses Postgresql as DBMS. To write client application do I need libpq library and header files? If yes where I would get libpq library and header files.

Answer 1

Libpq is included in the full PostgreSQL source code. You can use just libpq without the rest of PostgreSQL, but must download the full package.

You can download it from the PostgreSQL Downloads page.

Once you extract the full package it is inside srcinterfaceslibpq.

The PostgreSQL installation guide details how to install only the client libraries in the Installation section, under Client-only installation.

Libpq documentation is also available.
