I really don't see how that is possible.  A Postgresql sequence when
used in a Serial Type only generates a value on a insert.
I have tons of views that reference tables with columns that are serial
and they don't regenerate themselves when I sort the table in Access.
Not to mention PG views are read only ( unless you have some rules
defined)  The only problem we have had with sorting in access is with
varchars used as function OUT params which Access thinks are memo fields
and we got around that using views that cast them to varchars with lengths.

You have me totally lost as to the problem you are really having :-)
