It's awkward to work with, and the new GEOS provides better performance anyway. It's still useful for improving performance of intersects queries, though. | |
| Sep 30, 2021 at 18:46 | comment | added | dr_jts | Excellent news. GEOS 3.9 also implements an optimization for intersection with large geometries, so that might be helping here as well. | |

| Sep 29, 2021 at 17:49 | comment | added | swiss_knight | Hmm, interesting. I'll give one of the available PG14-beta based image a try then, because I cannot figure out a PostGIS image based on PG13 which relies on a GEOS version > than 3.7.x (but I may have missed it). | |

| Sep 29, 2021 at 16:16 | comment | added | dr_jts | What PostGIS version? This is likely fixed by GEOS 3.9 and up. | |
