Is it possible to configure Postgres to behave like Access - a single user
and use as much of the recourses as required?

Thanks,

Jay.

Because Access is not a multi-user database management system designed
to handle anywhere from a couple to several thousand users at the same
time?

PostgreSQL can do this update while still allowing users to access the
data in the database, and can handle updates to the same table at the
same time, as long as they aren't hitting the same rows.

They're two entirely different beasts.

One is good at batch processing moderate amounts of data for one user at
a time.  The other is good for real time processing of very large
amounts of data for a fairly large number of users while running at an
acceptable, if slower speed.

TIP 9: In versions below 8.0, the planner will ignore your desire to
       choose an index scan if your joining column's datatypes do not
       match
