Thread: Question about upgrading extensions

If one releases an extension with say a version number of 0.1 and then releases one with important changes at 0.2, how is the best way to manage these changes?  I couldn't find anything in the docs to discuss this issue.  Am I missing something?

Into pg_message_queue--0.1--0.2.sql.

See
http://www.postgresql.org/docs/current/static/extend-extensions.html#AEN

The command to upgrade an extension is ALTER EXTENSION UPDATE.
