Remove usage of _CDB_Geometry_SRID #154
Remove usage of _CDB_Geometry_SRID #154

This is only used from _CDB_Has_Usable_Geom. It doesn't do what's
promised in the comment. The effect is that a column is taken as valid
when it actually needs setting its SRID restriction so better not use
it as it will need rewrite anyway.
