Can anyone tell me if PostrgreSQL version 9.4.5 will work with ArcGIS 10.3.1? I can only find minimum requirements, but nothing about newer versions. I know in the past it has been fussy!
Hi Laura, maybe this thread could be of interest for you, just in case you did not find it by yourself already.
PostgreSQL9.4/PostGIS 2.1.7. with AGS 10.3/SDE enterprise multiuser
No, PostgreSQL 9.4.x is not supported with any released versions of ArcGIS yet.
