Hi,

In PostGIS 2.0, default SRID changed from -1 to 0 to conform to SQL-MM
standard.

I would like to know if -1 srid is completely discarded as suggested by the
behaviour of
AddGeometryColumn() which automatically change -1 value to 0

Or if it is reserved to unknown projected coordinate system as specified in
SpatiaLite 4.0
https://www.gaia-gis.it/fossil/libspatialite/wiki?name=switching-to-4.0

Thanks,

Michaël
