I also have the same problem, but I'm only using the Create Enterprise Geodatabase processing GUI tool: PostgreSQL 9.3.12 Windows 2012 R2 EC2 ArcGIS 10.3.1 for Desktop Advanced 64 bit background processing installed I haven't tried running Python scripts to solve this, but it seems like (based on the original post) it wouldn't help. I tried the exact same process on my local machine and everything worked perfectly. I haven't tried another physical machine or another VM in my own network yet. Any thoughts?
