I am attempting to Upgrade Geodatabase and the following error prevents the upgrade.
"Connected RDBMS instance is not setup for ST_GEOMETRY configuration.You must copy the latest ST_GEOMETRY library to the PostgreSQL software location"
The GDB was created a couple of years ago using ArcMap 10.3.1, very recently ArcMap was upgraded to 10.6
PostgreSQL 9.3.5 is running on Windows Server 2012 R2
The original st_geometry file exists in PostgreSQL lib folder. Since the error message suggests the latest ST_GEOMETRY file needs to be copied, I've tried copying the files from DataSupport folder in Postgres 9.4, 9.5, 9.6 but that wouldn't even allow connections to be made.
Also the libeay32.dll, libpg.dll,libintl-8.dll and ssleay32.dll files are in the intended location.
Any ideas any help will be much appreciated
