Problem installing with paid host

[Central/HQ]

My host provider "Media Layer" is telling me they can not install the 
dbd::pg module because they do not support postgresql and it is looking 
for the database on that server. I have a server for the database at my 
location and want to run "RT" from my host. Is this true or can it be 
installed without the database in place?
Thank You In Advance,
