Revert last commit. It was supposed to only be on 6.x-fulltest branch.
Fix sql-drop for sqlite. It has been busted since June - no bug report AFAIK.
Add a missing character to the postgres regex in the sqlConnect test case.
Merge branch '6.x' into 6.x-fulltest
Restore full test coverage except for php5.4 which we can skip under the assumption that its bugs will be caught by 5.3 or 5.5 tests.
