Hello @Muthu,
Welcome to Microsoft Q&A forum.
There’s no direct PostgreSQL project template in Visual Studio 2022.
This document: PostgreSQL says:
Many third parties provide NuGet packages for using PostgreSQL from .NET applications. You can browse the offerings in the NuGet Package Manager (Tools > NuGet Package Manager > Manage NuGet Packages for Solution). Perhaps, the most popular package is provided by npgsql.org.
Not sure if you want to use PostgreSQL in .NET applications, you can search to check if some NuGet packages meet your requirements.
I would also suggest you kindly post this question on PostgreSQL related forums for better help.
Thanks for your understanding, wish you a wonderful day ahead :)
Sincerely,
Tianyu
