Change SQL commands embedded in the initdb script from the style
echo "command" | postgres to the style postgres <<EOF command EOF This makes the script more legible (IMHO anyway) by reducing the need to escape quotes, and allows us to execute successive SQL commands in a single standalone-backend run, rather than needing to start a new standalone backend for each command. With all the CREATE VIEWs that are getting done now, this makes for a rather substantial reduction in the runtime of initdb. (Some of us do initdb often enough to care how long it runs ;-).)
