Re: unbale to use pg_ctl in Windows Cmd.

You've got to do it because Postgresql requires you to.

Or you could set PGDATA=C:\Program Files\PostgreSQL\13\data'and run pg_ctl status, just like the error message aid.

Problem resolved. But I just don’t know why.
So I need to add the data directory. like pg_ctl status -D 'C:\Program Files\PostgreSQL\13\data'

You will have to find it to use pg_ctl

Doesn't do any good if that's not where the data directory is.
