https://github.com/apache/madlib/pull/271
w/ @orhankislal The reason we had to change the info messages that are
printed during install/reinstall/upgrade is that we are now writing all the
necessary SQL into a single file, and running it as an atomic operation.
Previously, the messages were getting printed after individual modules were
processed. If we keep the older info messages as is, it won't reflect what is
happening underneath. Breaking the SQL file up to print messages will defeat
the purpose of this PR.
