Hi @Uday Kiran Reddy (ureddy) Thank you for posting your question on Microsoft Q&A and for using Azure services.
My understanding is that you are able to create an Azure PostgreSQL flexible server using ARM templates but cannot find a way to create tables as part of the template. Please let me know if my understanding is not correct.
Unfortunately, there is no API to create a table in azure PostgreSQL, not even from the portal. That has to connect to server to do so.
Regards,
Oury
