#571 Support of Postgres spatial data (GIS)

[LeO]

I connect to a Postgres DB with the GIS-driver. When quering some tables (e.g. address) the results where a PGPoint is stored is always displayed as <other></other> Opening with the Postgres client show the spatial data by default. I cannot set any properties in the driver details additionally.

==> my request
display the data type properly
show the data content properly
