In commit 4317e0246c645f60c39e6572644cff1cb03b4c65, I accidentally broke this behavior while rearranging code to ensure that --create wouldn't affect whether a DATABASE entry gets put into archive-format output. Thus, 9.2 would issue a DROP DATABASE command in --clean mode, which is either useless or dangerous depending on the usage scenario. It should not do that, and no longer does. A bright spot is that this refactoring makes it easy to allow the combination of --clean and --create to work sensibly, ie, emit DROP DATABASE then CREATE DATABASE before reconnecting. Ordinarily we'd consider that a feature addition and not back-patch it, but it seems silly to not include the extra couple of lines required in the 9.2 version of the code. Per report from Guillaume Lelarge, though this is slightly more extensive than his proposed patch.
