-------------------------+--------------------------------------------------

Comment(by strk):
I was wrong about the new ST_IsValid support being available in 1.5.3.
It is in 2.0, togheter with ST_MakeValid:
{{{
strk=# select postgis_full_version();
postgis_full_version
-------------------------------------------------------------------------------------------------------------
POSTGIS="2.0.0SVN" GEOS="3.4.0dev-CAPI-1.8.0" PROJ="Rel. 4.7.1, 23
September 2009" LIBXML="2.7.6" USE_STATS
(1 row)
strk=# select gid, st_isvalid(the_geom) from geosbug;
gid | st_isvalid
-------+------------
12202 | f
(1 row)
strk=# select gid, st_isvalidreason(the_geom) from geosbug;
gid | st_isvalidreason
-------+---------------------------------------------------------------------
12202 | IllegalArgumentException: point array must contain 0 or >1
elements
:
(1 row)
strk=# select gid, st_astext(st_makevalid(the_geom)) from geosbug;
gid | st_astext
-------+-----------------------------------
12202 | MULTIPOINT(1737689.37 5082819.07)
(1 row)
}}}
I don't know if this is worth backporting to 1.5 (the ST_IsValid part)
