Add --no-instructions parameter to initdb
Specifying this parameter removes the informational messages about howto start the server. This is intended for use by wrappers in differentpackaging systems, where those instructions would most likely be wronganyway, but the other output from initdb would still be useful (and thusjust redirecting everything to /dev/null would be bad).Author: Magnus HaganderReviewed-By: Peter EisentrautDiscusion:https://postgr.es/m/CABUevEzo4t5bmTXF0_B9WzmuWpVbMpkNZZiGvzV8NZa-=fPqeQ@mail.gmail.com
