It's definitely in my path.  And stays there, even when I run sub-processes
(which I thought might be the problem, after you mentioned it).

bash-4.2$ pg_ctl

pg_ctl: no operation specified

Try "pg_ctl --help" for more information.

bash-4.2$ type pg_ctl

pg_ctl is hashed (/opt/rh/rh-postgresql12/root/usr/bin/pg_ctl)

bash-4.2$ echo $PATH

/opt/rh/rh-postgresql12/root/usr/bin:/opt/app-root/src/bin:/opt/app-root/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

bash-4.2$ bash

bash-4.2$ echo $PATH

/opt/rh/rh-postgresql12/root/usr/bin:/opt/app-root/src/bin:/opt/app-root/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

bash-4.2$ exit

exit

bash-4.2$ bash -c 'echo $PATH'
