<div dir="ltr"><div>Does someone know why ST_Union behaves differently with linestrings and polygons?</div><div><br></div><div>If a table contains linestrings that overlap at some points then ST_Union creates a collection of linestringsĀ that are splitted at intersections.</div><div><br></div><div>If a table contains polygons with overlaps then
ST_Union creates a collection of polygons that are still overlapped and are not splitted (the result contains only the original polygons).</div><div><br></div><div>Thanks in advance.</div><div><br></div><div>Antonio<br></div><div><br></div><div><br></div></div>
