Version 2.28 (release notes) of the GNU C library introduces many changes to the collations it provides. Collations determine how strings are compared and by default, PostgreSQL uses the operating system’s collations which on Linux means glibC.

This unexpected change in the order of indexes will lead to incorrectly ordered query results and possible data corruption. Currently, the following distributions are affected:
