Unable to create database in postgresql using round house tool and .net core

[pavankog]

I have postgresql localhost database installed in to my machine and try to create table using round house tool, I'm getting the below error

RoundhousE encountered an error. System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
command I have tried to execute:

"D:\Users\myusername\.dotnet\tools\rh.exe" rh.redgate.diff /d="TestRoundhousE" /f="D:\Users\myusername\Desktop\Round\roundhouse\db\PostgreSQL" /s="PostgreSQL 14" /vf="_BuildInfo.xml" /vx="//buildInfo/version" /r="https://github.com/chucknorris/roundhouse.git" /env=LOCAL /simple

pause
