Connecting to PostgresSQL hosted on AWS RDS?

[edwardrmiles]

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)

I ran into the same error, and disabling encryption will also make that error go away. 

To disable encryption

1. File --> Options and settings --> Data source settings
2. Click Edit Permissions on your connection
3. Uncheck Encrypt Connections

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 certificate 

3. Apply the Certificate

4. Download and Install On-premises data gateway

Hello @aqavi10 , @edwardrmiles , @aletorres_BI ,

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 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 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,

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.

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,
Lydia Zhang

@v-yuezhe-msft 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

Thank you. This is beyond my skills. I will elevate this to our IT group.

Hi. I am trying to connect AWS sql postgres with power bi and I have got several errors, you have an idea what may be the problem (problem is An error occurred while reading data from the provider: 'The remote certificate is invalid according to the validation procedure.' ") I found this forum but this solution does not work for me either, l

[aqavi10]

@alvaroborquez : I have updated the gdrive link in my previous reply which should help you download the remote certificate. However, please follow the instructions available in the Microsoft url attached previously in order to convert the certificate and install it. Try restarting power BI or your PC once you are done installing the certificate and give it a go. Also, please post screenshots of the errors and the steps you have tried prior to seeking help.

Hi @aletorres_BI ,

  Please check your inbox. I'll try doing whatever I can.

Hi everybody, I solve my issue following these steps:

1.- Install Npgsql using Visual Studio.

First, create a new project by default options.

Second, in References select Manage NuGet packages...

Third, Browse Npgsql and install it.

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)

4. Install certificate using right-click in the mouse.

5. Move certificate from Current user to Local computer using MMC command.

[aletorres_BI]

Sorry, I can't add pictures to steps 4 and 5.

So, in step 4 right-click and select install certificate

Select where you want to put all certificates, I select Trusted Root Certification Authorities

5. Move the certificate from Current user - Trusted Root Certification Authorities to Local Computer - Trusted Root Certification Authorities using MMC command.

Hello everyone,

thanks @aletorres_BI this is great help. It is working on my local computer with my local gateway - just perfect. However after installing everything to my remote server (also windows 10 frontend) with the same steps involved. I will always get an error code when I want to enter my credentials for this dataset. It is not working. 

I am using the latest Gateway version

Do you have a  clou why?

[alvaroborquez]

Hi aqavi10

 I followed all the steps indicated in the comment, the error still persists.
Download the certificate...
