A great cross-platform compiler, both Borland Pascal & Delphi compatible. http://tfdec1.fys.kuleuven.ac.be/~michael/fpc/ On the contributed units page, you will find a postgres unit, which is a pascal wrapper for libpq (postgres 'c' library). I have been using this for about a year now on Linux. Works wonderfully and allows me to stay with the language of my choice ;-). GPC is another cross-platform compiler more focused on portability than FPC. It can also wrap 'c' libraries, but I have no experience with it yet. Cheers!
