See the Free Pascal page. 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!
