Probably.
Although in my humble opinion, proposing postgres 7.3 in 2006 is a bit
disrespectful to the considerable work that has been done by the postgres
team since that release.
If you don't find a host to your liking, and you have a large website, as
you say, consider a dedicated server. Prices are quite accessible now, you
can install the latest version of Postgres. Going from 7.3 to 8.1, and
having your own server with all its resources dedicated to running your
site, will probably enhance your performance. Consider lighttpd which is a
speed demon and uses very little resources.
