coulduse PhpPgAdmin, but the hints on the web don't seem to work. One said to simply get a dump from one phpPgAdmin,
thego to the other server, select the database, click the SQL button and then select the dump file. When I do this the
importfails because the dump file begins with a \connect statement. The escape char doesn't seem to go through the web
frontendor something. But without the connect statement it ends up telling me no database selected. Please, can someone
letme know how to do this? 

command line tools and simple scripting are the way to do this.  it
works equally well on *nix and windows.  a simple script might be:

psql -h restoredb -c "drop database if exists mydb"
psql -h restoredb -c "create database mydb"
pg_dump -h dumpdb | psql restoredb

you'll probably want to add some logging and error checking (this will
work differently depending on o/s) but that's the basic mechanism.
Once you have it scripted, it then becomes a matter of scheduling the
backup and restore.

Another fancier approach to dealing with this is to look at setting up
replication.
