I assume you mean you wish to upgrade your 7.4 installation of 
PostgreSQL to PostgreSQL 8.1 ?

The short answer:

You'll need to start the 7.4 version of the server, with your old data 
directory and run the version of 'pg_dumpall' that comes with PostgreSQL 
8.1 .  Once you've generated a dump and saved it, you can install 8.1 
and then use the 'psql' utility to re-load the dump on 8.1 .  The 7.4 
data directory isn't compatible with 8.1, so you'll need to perform the 
dump and subsequent restore.

You'll probably also want to go through the 7.4 pg_hba.conf and 
postgresql.conf files and port over any changes you need that are 8.1 
compatible.
