pg_ctl: command not found

Hi,

If you can not reach pg_ctl command in bash also you are sure this command exists in your server, check $PATH.

-bash-4.2$ echo $PATH
/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin

So, the directory of pg_ctl is not seem in PATH. Input directory of pg_ctl and check it then run it.

-bash-4.2$ export PATH=$PATH:/usr/pgsql-9.6/bin/pg_ctl

-bash-4.2$ echo $PATH

/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/pgsql-9.6/bin/pg_ctl

-bash-4.2$ pg_ctl --help
