pg_restore and permissions

Is there a simple way to restore a databases from a pg_dump file?
I've got a "pg_dump -F c" from version 7.1.3 and would like to restore
it on a 7.2.1 database server.

However, if I invoke, say, "pg_restore -C -d web web.db", I get the
following error message:

pg_restore: [archiver (db)] could not reconnect to database: FATAL 1: IDENT authentication failed for user "www-data"

My pg_hba.conf looks like this:

local all ident sameuser
host all 127.0.0.1 255.0.0.0 ident sameuser
host all 0.0.0.0 0.0.0.0 reject

I know how to work around this problem (and did it in the past), but
I'd really like to be able to restore a database using a single
command. Does such a command exist?
