Which is the data source from which you import the data (e.g. textual,
etc.)?

If I've correctly understood, you have arrays where geospatial and
non-geospatial information
is present, each one providing a "dimension" of the array.

Just FYI, in PostGIS is possible to define mixed, structured data with
constructors like POINTM
and POINT, that allow to add a further dimension to the 2D/3D
(respectively) geospatial ones, that
includes a scalar information.

Hope this can help in your import, otherwise provide more information about
source data and how
you'd like to import.

Giuseppe.
