Connecting to PostgresSQL hosted on AWS RDS?
Has anyone managed to do connect to PostgresSQL hosted on AWS RDS? if so how did you do it?
It appears from a few forum and ideas posts that it wasn't possible when PBI was released but I was wondering if the situation had changed or perhpas someone had come up with a work around?
(ps I know there is a PostgresSQL on-prem connector and AWS Redshift connector)
Anonymous the PostgresSQL connector doesn't work out of the box, you need to do quite a few things first
1. Install Npgsql which allows .NET access to PostgresSQL. I installed it using the Pakagae Manager Console in Visual Studio; detailed instructions are here: https://www.nuget.org/packages/Npgsql/
You need to connect over SSL to AWS which isn't setup by default (on my Windows 10 machine anway)
2. Download the AWS public key from here https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem
3. Convert that to a certificate using https://www.sslshopper.com/ssl-converter.html (convert to PKCS#7/P7B)
4. Import that certificate to the Trusted Room Certificate described here http://www.cs.virginia.edu/~gsw2c/GridToolsDir/Documentation/ImportTrustedCertificates.htm
5. Test access from Power BI desktop using the PostgresSQL connector and it should work
In conclusion it's possible to connect to PostgresSQL on AWS RDS databases but it isn't easy

I ran into the same error, and disabling encryption will also make that error go away.
To disable encryption
- File --> Options and settings --> Data source settings
- Click Edit Permissions on your connection
- Uncheck Encrypt Connections
This totally worked for me.
Thank you!
I am struggling with the same issue connecting power bi to couldSql database on GCP.
It doesn't work if i select a direct PostgreSQL connection. Error is 'The remote certificate is invalid according to the validation procedure'.
But if I use ODBC and set 'sslMode=required' then the connection works. (I must to use direct PostgreSQL connection for my solution).
Anyone faced similar issue? it's very urgent for me unfortunately, thanks in advance!Recently Amazon changed the link to download the certificate. To download the latest certificate go to: Using SSL/TLS to encrypt a connection to a DB instance or cluster - Amazon Relational Database Service
Download the global-bundle.p7b or the bundle that corresponds to the region of the RDS. Then add certificate to Trusted Root Certificate.
Hi edwardrmiles，
Have you tried to use the on-pre PostgreSQL connector in Power BI Desktop to connect to PostgreSQL hosted on AWS RDS? What problem do you get?
Thanks,

AWS makes their certificate bundles available in the correct format so you don't need to convert.
You can download the bundle for specific regions from: Certificate bundles for specific AWS Regions
I tried these instructions above, but i need to figure out another detail: you need to specify the host full name (e.g: mydb-production-read.sdjalsajdlskja3j.sa-east.rds.amazon.com) not the friendly name behind your dns.
I tried connect with the internal name of our vpc, like mydatabase.prod.mycompany.com and fail because this host isn't especified on amazon certificate.""Npgsql.Tls.ClientAbortException: Certificate Unknown: Server certificate was not accepted. The specified hostname was not present in the certificate."
Hello,
Have you figured this out? I am facing the same problem and done the above instructions, given that I am giving a IP address for the server name.
Hello,
Have you figured out this? I am facing the same issue after doing the exact instructions above.
Given that I am providing the IP Address not the full Host name.
Hello aqavi10 , edwardrmiles , Anonymous ,
I have successfully followed all the instructions but still getting the "The remote certificate is invalid according to the validation procedure" error.
However, I'm missing the last step when moving certificates to "Local Computer". Indeed, I've no such folder on my machine :
Could it be the reason why I still get the error? What should I do to make it work?
Thanks a lot !

I have noticed that some links in the solution do not work.
Here is what I did:1. Install Npgsql
2. Download the AWS public key and convert it to a certificate3. Apply the Certificate
4. Download and Install On-premises data gateway
