#First I had to add the PostgreSQL administration commands to the PATH:
export PATH=$PATH:/usr/lib/postgresql/8.1/bin

#LOCAL_DB is the directory that will contain everything.
export LOCAL_DB=$PWD

#Setup the server
export PGDATA=$LOCAL_DB/data
initdb

#Start the server (no spaces in $LOCAL_DB !)
export PGHOST=$LOCAL_DB
pg_ctl -w -l server.log start -o "-c listen_addresses= -c unix_socket_directory=$LOCAL_DB"

#Create a database and an unprivileged user
createdb base
createuser -SDR client

#Run client commands
psql base client
