I think you can selectively move table/index files to another location and
create symbolic links from the original location.  The postmaster must be
stopped while you are doing this.

Keep in mind that Postgres will create separate files for each 1GB of a
table.  So if your table grows substantually after you set this up, new
segment files may have been created, thus partially undoing the effect you
were trying to achieve.
