pgsql v. Access pt Duex: the view

Ok, first thank you all who helped me with my last problem of trying to
get M$ Access to query and update a PostgreSQL database.  As, I am sure
it is rather evident, I am somewhat new to PostgreSQL (I played with the
"other" SQL DB)  I reasoned that if I could get Access to update tables
directly with no problems, and if all a VIEW is is just a table based on
a set of queries... (you see, I'm thinking here!) I dug in and found
that with the help of a RULE it became possible to UPDATE, INSERT, and
DELETE from a view!  So I played and, on the command line in 'psql', all
worked fine.  I made three little test tables, made a view that SELECTed
a few choice items from each, and was able to UPDATE any column I
wanted. (or that I had a RULE for).  I tested it with just one UPDATE
rule for my VIEW in Access, and... IT WORKED!  I was able to update the
VIEW!  My hopes were high! So I found out that I could slap () around a
bunch of UPDATEs so I could end up UPDATing all three test tables from
the VIEW.  But then I went back to Access... I found that Access would
only UPDATE the LAST in the list of UPDATEs in the RULE and it would
give me messages that "someone else was in the porcess of updating this
table, try again later" if I tryed to UPDATE a column that was not the
last column in the RULE list... Am I making sense?  Has anyone else
tried this?  Am I close to my answer?  My other thought was to make a
function, but that's new to me too...  For those new to my plight, I am
trying to migrate an Access database to PostgreSQL (That is NOT the
problem), but the users are all used to making the queries in Access and
making reports and such.  I am trying to make it as painless and as
seamless for them as possiable.  They are used to being able to make a
query based on many tables, and being able to update the database
directly from the result of the query.  I have learned that most real
RDBMS do not, and should not, work that way. So... That brings me back
to this post. :)
