Re: Importing csv files containing multiple geometries in postgis

Dear Selcuk,

Thank you very much again for the reply.

Yes, I can control the geometry. Is there some way by which I may
convert the following "invalid" polygon geometry to "valid" in
postgis:

INSERT INTO mygis_table( poly) VALUES(
ST_GeomFromText('POLYGON(-5.8335446 43.3655635,-5.8336337
43.3655207,-5.8349218 43.3673341,-5.8345197 43.3674013,-5.8336182
43.3660938,-5.8335037 43.365924,-5.8334505 43.3658461,-5.8334702
43.3657311,-5.8335446 43.3655635)', 4326));
