[postgis-users] Is there a better way to apply ST_Difference?

[DavidRA]

Hello, this is the issue: I have two tables with several geometries and I'm
trying to obtain the elements stored in the first one but without the
regions where they intersect with an element stored in the second. By now, I
use this:



But I'm not sure if there is a better way to do this, something that could
present a better performance (in comparision with a similar operation like
intersection, it's very slow). Thanks!
