Installation on Web Server

[Richard Hayward <richard(at)tortoise(dot)demon(dot)co(dot)uk>]

I'm wanting to install PHP on a Apache/Linux server with support for
PostgreSQL.

It seems that I need to install PostgreSQL on the machine first,
before the PHP installation will work.

The way I've done this previously is simply to install PostgreSQL.
However, the database server is in fact another machine, so another
full install of it on the web server seems redundant. All the
instructions I've found assume that web and database servers are
running on the same host.

Is there some (easy !) way to install just the minimum parts of
PostgreSQL I need on the web server?

Regards

Richard
