Error: scheduler type postgres is not one of [objectstore, pgsched]. command terminated with exit code 1

There is inconsistency in what build_deploy.sh, build_srpm.sh and build_rpm.sh scripts expect and check as the value for --scheduler-type parameter. It does check for "pgsched" or "objectstore" as values, but expects "postgres" or "objectstore" at other places.
