Previously, psql printed only the last result if a command string returned multiple result sets. Now it prints all of them. The previous behavior can be obtained by setting the psql variable SHOW_ALL_RESULTS to off. This is a significantly enhanced version of 3a5130672296ed4e682403a77a9a3ad3d21cef75 (that was later reverted). There is also much more test coverage for various psql features now.
