[postgis-users] POLYGON from LINESTRING

[Paul Ramsey]

Hm.
No there is not a simple way. Type casting is not specified in SFSQL. I
guess it behooves me to ask why you are loading your polygons as
linestrings?
(The non simple way is to extract them, re-write their types as POLYGON
and re-insert them.)
