C:\Users\Think>pg_ctl --help
pg_ctl is a utility to initialize, start, stop, or control a PostgreSQL server.
I don't know where the pg_data directory. So I set the C:\Users\Think\Desktop\postgres\data as user variable and system variable In windows setting. But still not working. In the bin directory, there is pg_ctl.exe file.
