Relational-database-can't-access-instructions

When I started the project it was missing the instructions part.
The file I created on my last save was still there .
I can’t connect to the database.

There was this error message when I tried to access database.

psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory
        Is the server running locally and accepting connections on that socket?

I opened Command Pallete : CodeRoad:Start
and it show this error message
Command 'CodeRoad: Start' resulted in an error (command 'coderoad.start' not found)

when it does that you may need to restart the virtual machine

look at this
