@paelzer Thank you for the triaging and the detailed explanation. Since this change slipped in too long ago I don't think it should be reverted. I think Postresql could check if there was a change in sorting compared to the which the indices were created with, but this installation does not uses Postgresql from the archive so that would just be an unrelated improvement. Maybe Postgres already does that.

Before Ubuntu upgrade following command result was: [code] vodka@ubuntu140:~$ ( echo "1-1"; echo "11" ) | LC_COLLATE=en_US.UTF-8 sort 1-1 11 [/code] But after upgrading Ubuntu 18.04 to latest release via apt upgrade (18.04.5) result of the command above totally changed: [code] vodka@ubuntu140:~$ ( echo "1-1"; echo "11" ) | LC_COLLATE=en_US.UTF-8 sort 11 1-1 [/code] Due to this our production Postgres database started work very slowly and we had a long downtime for REINDEX. Sorting method is very important for Postgres database: https://wiki.postgresql.org/wiki/Locale_data_changes Please, read "Testing collation" part. Is it normal behavior for Ubuntu? Why glibc totally changed within LTS release without 'major upgrade'? I did not expect this...
