Unified Docs Switcher 作者: Doug Harris

You're looking at documentation but not the right version. The syntax is probably the same but you've been doing this long enough to know better, so you want the correct version.

This browser extension remembers which version of documentation you're using for programming languages, frameworks, databases, etc.

Currently handles docs for PostgreSQL, Python, Django, and Celery.
