Title: Major changes in sorting method upgrade 18.04->18.04.5 due to base- files change Status in base-files package in Ubuntu: New Status in glibc package in Ubuntu: Invalid Status in postgresql-10 package in Ubuntu: Invalid Status in base-files source package in Bionic: New Bug description: I had an Ubuntu 18.04.0 with Postgres 9.6. 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...
