PostGIS technically saves the SRID as part of each individual geometry.
The OpenGIS standard mandates that all geometries in a single table
column have equal SRIDs, and that the geometry_columns table contains
the information which SRID that is. But PostGIS itsself can be used
more freely, dropping OpenGIS conformance however.
