Connecting to PostgresSQL hosted on AWS RDS?
- 9 years ago
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 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.
