Which version of GEOS do you have ? SELECT postgis_full_version(); Try upgrading to latest (3.3.5) If it still fails consider reducing the input pair till it's small enough to be attached as HEXWKB to a ticket. As a workaround you could try shaking the vertices with something like ST_SnapToGrid (and maybe ST_UnaryUnion on the result to ensure validity on collapse). --strk; Sent from our free software http://www.gnu.org/philosophy/free-sw.html _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
