-- Update to support pgBouncer 1.18.0. Note that as of v0.5, this extension requires at least version 1.18.0 of pgBouncer. If you still need to support an older version, v0.4 works with pgBouncer 1.16 and v0.3 works with older versions of pgBouncer. There are no other changes in this version other than a compatibility update.
-- Several views are dropped and recreated as part of this update. Privileges should be preserved, but it is recommended to double-check them.
