but it is not documented in psql documentation

please check below two lines .

Allow quit and exit to exit psql when given with no prior input (Bruce
Momjian)

Also print hints about how to exit when quit and exit are used alone on a
line while the input buffer is not empty. Add a similar hint for help.

Thanks,
Mohamed Ali .
