Thread: DBD::Pg without Postgresql installed
I should know the answer to this, but I don't--Is it possible to install DBD::Pg without Postgresql being installed? Trying from CPAN seems to imply not (pg_config needed). Just wanted confirmation.... Thanks, Sean

DBD::Pg links against libpq, so to build it you need that library and header files like libpq-fe.h; as you've discovered, the module uses pg_config to learn about where things are installed. At runtime you'll probably need at least the libpq.so shared library. You shouldn't need to have a server running or even installed, but you'll need at least some kind of client installation. -- Michael Fuhr http://www.fuhr.org/~mfuhr/

Just to follow-up, are there sources to build just a client installation? It looks to me like not. I don't have a problem building a server on each workstation that will be accessing postgres, but if there is a way to keep things cleaner and install only the client (or client libraries), that would be great. Thanks again, Sean

I'm not aware of a simple way to build just a client installation with the standard sources, but some vendors provide pre-built, client-only packages. Even if you're building from source, you could easily wrap your own client-only package for installation on other systems (assuming compatible platforms). If you don't intend to build anything on those other systems, then you might need only libpq.so and perhaps a few other files (psql, pg_dump, etc.); otherwise you'll also want header files and programs like pg_config. -- Michael Fuhr http://www.fuhr.org/~mfuhr/
