Find your binaries file where it is saved. get the path in terminal mine is
C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin
then find your local user data path, it is in mostly
C:\usr\local\pgsql\data
now all we have to hit the following command in the binary terminal path:
C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin>pg_ctl -D "C:\usr\local\pgsql\data" start
done!
