Commits 83dec5a712 and ff402ae11b taught vacuumdb to reuse passwords instead of prompting repeatedly. However, the docs still warn about repeated prompts, and this improvement was not applied to clusterdb and reindexdb. This commit allows clusterdb and reindexdb to reuse passwords just like vacuumdb does, and it expunges the aforementioned warnings from the docs.
