Microsoft access verses postgresql

I've got a client who is following my suggestion that they replace a set
of excel spreadsheets with a database solution.  They are looking at two
proposals, postgresql solution or an Access solution.  The requirements
will include vpn connectivity from one site to another.  It appears they
will be going with the Access solution.  I've got concerns regarding
this based on research I've done that seems to indicate that Access,
when used in a multi-user solution is easily corrupted.  Does anyone
have any knowledge/experience with such issues?
