Hi, I am trying to connect to a PostGreSQL database that is in the cloud hosted by the Clinical Trials Collaboration Initiative.
I am trying to conduct research on clinical trials and this service provides data updated daily for researchers.
The credentials to use are (this is public information)
Hostname: aact-prod.cr4nrslb1lw7.us-east-1.rds.amazonaws.com
Port: 5432
Database name: aact
User name: aact
Password: aact
But then I get the following error:
Details: "An error happened while reading data from the provider: 'Could not load file or assembly 'Mono.Security, Version=4.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756' or one of its dependencies. The system cannot find the file specified.'"
I am using PowerBi Desktop installed in Windows 10.
Any idea what might be going on?
Thanks.
@juanpablo @gcanelon were you able to resolve this? running into the same issue now myself. thanks!
Hi @gcanelon,
Based on the above error message, the issue is related to npgsql installation. Please Download and unzip the most recent Ngpsql data provider for PostgreSQL, then use GACUtil.exe to add Mono.Security.dll to the global cache.
There is a similar article for your reference.

Hi. We were able to get this working directly (not via ODBC), but I am left wandering: I want to publish this to the web and have it update periodically, with a database on the cloud.
Do I need a gateway? It seems odd to need a machine inside my network to connect a thing in the cloud (BI) with another thing in the cloud (postgres).
