Nouvelle version : PostGIS<\/a> 3.6.0<\/strong> (Publi\u00e9e le 2 septembre 2025)<\/p>\n\n\n\n

PostGIS 3.6.0<\/strong> est disponible depuis le 2 septembre 2025<\/strong>. Elle est con\u00e7ue pour fonctionner avec PostgreSQL 12 \u00e0 18 beta 3<\/strong>, n\u00e9cessite GEOS 3.8+<\/strong> (avec des optimisations pour GEOS 3.14+) et Proj 6.1+<\/strong>. Pour activer toutes les fonctionnalit\u00e9s de SFCGAL<\/strong>, la version 2.2.0+<\/strong> est requise.(PostGIS<\/a>)<\/p>\n\n\n\n

PostGIS est l\u2019extension spatiale la plus utilis\u00e9e pour PostgreSQL, mais sa disponibilit\u00e9 varie selon le syst\u00e8me d\u2019exploitation et la version de PostgreSQL. Il est important de choisir la version stable adapt\u00e9e \u00e0 votre environnement pour \u00e9viter les probl\u00e8mes de compatibilit\u00e9 et assurer la fiabilit\u00e9 de vos traitements g\u00e9ospatiaux.<\/p>\n\n\n\n
Le tableau ci-dessous r\u00e9sume les versions stables et exp\u00e9rimentales disponibles selon les principaux syst\u00e8mes\u202f:<\/p>\n\n\n\n

La version 3.6<\/strong> n\u2019est pas encore officiellement disponible sur Windows.<\/li>\n\n\n\n
Les versions exp\u00e9rimentales sont destin\u00e9es uniquement aux tests et \u00e0 la d\u00e9couverte des nouvelles fonctionnalit\u00e9s.<\/li>\n\n\n\n
Sur Windows, StackBuilder facilite l\u2019installation et la mise \u00e0 jour des d\u00e9pendances.<\/li>\n\n\n\n
Sur Linux, la compilation depuis les sources permet d\u2019acc\u00e9der aux derni\u00e8res fonctionnalit\u00e9s, mais n\u00e9cessite une configuration correcte de PostgreSQL et des biblioth\u00e8ques de d\u00e9veloppement.<\/li>\n<\/ul>\n\n\n\n
