Subject: [PATCH] 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 ;-).)
