GDAL, Mapserver and PostGIS

[Angus Dickey]

Hello all,

I notice both GDAL and Mapserver have options to be compiled with support for PostGIS. Is it necessary to compile PostGIS support into GDAL as well as the Mapserver executable? Also do Postgresql/PostGIS have to be installed on the machine compiling (then running) Mapserver? Or are there just certain PostGIS libraries that can be applied?

Thanks for any help,
