Ticket #93 (closed task: fixed)
ST_Extent() and ST_Estimated_Extent() return BOX2DFLOAT4s
|Reported by:||mcayland||Owned by:||mcayland|
Description (last modified by robe) (diff)
In the case of ST_Extent(), this is serious because it means that ST_Extent(col) will never return the exact extent of a column - it will always be inflated by a small amount due to the extra conversion between BOX3D and BOX2DFLOAT4.
* BOX2DFLOAT4s should never be exposed to the user, especially in that ST_Extent() returns a string containing BOX (a legacy PostgreSQL type) rather than BOX3D *
ST_Estimated_Extent() should also return a string beginning 'BOX3D' for the same reason.
