ArcGIS Pro V 3.5.1 ST_Geometry version supported

[RachelMba1]

Hello. I am working on installing PostgreSQL and successfully using it on my ArcGIS Pro. I am using ArcGIS Pro version 3.5.1, and I also downloaded the ArcGIS Pro ST_geometry Library (PostgreSQL). The challenge I am encountering is that I do not know the version of ST_Geometry supported by ArcGIS Pro 3.5.1. I will need this information so that I can copy that .dll file to my Postgres V 15.13 file. 

I will appreciate any clues to help.

Upgrade the ST_Geometry type in a PostgreSQL database—ArcGIS Pro | Documentation

says

Download a new version of the st_geometry library from My Esri.

I don't use it, so you will have to check

Make sure you select the folder that says "15" then the OS of the PostgreSQL instance is installed on (Windows / Linux).

It is not needed if using RDS or similar instance in cloud

You're close! For ArcGIS Pro 3.5.1 with PostgreSQL 15.13, the supported ST_Geometry version is 5.0.0. You’ll find the .dll in the DatabaseSupport\PostgreSQL folder inside your ArcGIS Pro install directory — just match it to your Postgres version.

Also, I’ve shared some useful GIS resources (including free tools) here if you're interested:

Hope that helps!
