[postgis-users] Error database geometry requires more points - postgis 1.5

[Maria Eugenia Calle Peralta]

Hi:

We are working a database with postgis 1.5. (postgresql 9.1).  Around 30 users editing a hidrography table (multilinestring) together at
the same time using quantum gis. The last days we had a problem, when
viewing the layer at certain zoom objects disappear and the error is reported
"Error database geometry requires more points".


I check with the functions:
-ST_isvalid(), Geometry invalid not found.-ST_NumPoints(), All geometries have more than 2 vertex


The reference system is defined and even add a constraint verify_geometry_valid CHECK (st_isvalid(geom)) and the problem remains.
I dont kown where is the problem.




Thank you much help.
