I am trying to connect an PostgreSQL database made using pgAdmin 4 in ArcGIS Pro 2.0.1. PostgreSQL version is 10.0.

I tried several methods of connecting and how easy it is in QGIS I cannot find the reason why it doesn't work in ArcGIS Pro.

I followed the steps here, edited the pg_hba.conf file even by making so all connections to the database are allowed thinking this would be the issue but this didn't help.

I am configuring it like this now:

Database connection in ArcGIS pro

Where my database name in PGAdmin is this:

PGAdmin database list

I am using regular settings:

host name: localhost port: 5432 username: postgres

But yet, whatever I try, this error pops up:

Error message

What I am doing wrong? This is my first time doing it on ArcGIS Pro and I didn't have any problems using other software.

    Do not ever use the postgres user for trivial connection tests. Proper practice is to create a minimally privileged login (e.g. "test" or "proj1user"). You may be using an unsupported PostgreSQL release -- please edit the question to specify the exact PG version. Your problem is likely that your connection parameters are different -- localhost is not the same as vrowl (you must take proactive steps to permit connection on other than the loopback interface) – Vince Nov 30 '17 at 11:35

    PostgreSQL 10 is not yet supported by any Esri release. pro.arcgis.com/en/pro-app/help/data/databases/… – Vince Nov 30 '17 at 12:33
  • Well that explains it then. Thanks for the answer. Any indication when this will be supported? – B.Quaink Nov 30 '17 at 13:23
  • 10.6 is due out soon; it will likely support 9.6, but I'm not convinced 10.0 will make the cut. – Vince Dec 1 '17 at 3:31
  • I am having the same problem, using the 9.6 version of PostgreSQL and 2.1.3 have gone through same channels/processes as user stated above – Grace May 31 '18 at 12:41

Still no PostgreSQL 10 sadly.
