Suppose we have in PostGIS table with point geometry, ID column and
some other attributes.
Is it possible to create table with polygon/polyline geometry which is
linked to table with point geometry ?
I mean such a link where:
- geometry of polygon/polyline is not created by set of coordinates but
is created by (refering to) set of ID's from point table,
- when some point object (from point geometry table) is removed it
should automatically influence the shape of polygon/polyline.
