The IsValid function does not exist unless you have JTS/GEOS support.
Your geometry has nothing to do with this error message.
On the topic of your geometry, you can insert it, but in a planar
interpretation of lon/lat, which is what we have, it will not be
handled "right" in every case, and if it self-intersects in planar
space (a common situation for pole-covering things) it will be
"invalid". It will still be storable, though.

Hi,
is it possible to insert polygons into PostGIS where the polygon
"cross" the
north pole?
Example:
select isvalid('POLYGON((152.991022 78.938867,79.710092
68.321799,-50.514656
62.226884,-9.980464 56.376708, 152.991022 78.938867))');
ERROR: isvalid:: operation not implemented - compile PostGIS with
JTS or GEOS
support
Will it help to compile PostGIS with GEOS/JTS support?
cheers
