creating schemas in postgis is nondeterministic in which spatial type is
entered into geometry_columns
------------------------------------------------------------------------------------------------------
Key: GEOT-3157
URL: http://jira.codehaus.org/browse/GEOT-3157
Project: GeoTools
Issue Type: Bug
Components: data postgis
Affects Versions: 2.4.0
Environment: All
Reporter: Chris Van Orman
Assignee: Justin Deoliveira
The PostgisDataStore does not seem to be consistent in which spatial type is
entered into the geometry_columns table when creating a schema.
Looking at the source it would appear that the GEOM_TYPE_MAP HashMap is simply
iterated over and inserted into the GEOM_CLASS_MAPPING HashMap with the keys
and values reversed. However, the GEOM_TYPE_MAP is many-one (ie. POLYGON,
POLYGONM, CURVEPOLYGON all map to Polygon.class). So, when creating a schema
for a Polygon.class it is unclear whether the type inserted will be POLYGON,
POLYGONM, or CURVEPOLYGON (the order of a HashMap is not defined or guaranteed
to remain constant over time).
In version 2.3.0 the GEOM_TYPE_MAP was a one-one relationship and so this
problem did not show up until 2.4.0. Perhaps the GEOM_CLASS_MAPPING should be
independently generated?
