The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/18/collation.html Description:
Hi, Team ! It looks like the PostgreSQL documentation doesn't explain the customers what to do with PostgreSQL in case of OS system version upgrade or/and glibc / libicu version change. There're many links/blogs available where the required actions are explained. https://knowledge.enterprisedb.com/hc/en-us/articles/13520015051420-glibc-locale-data-changes https://www.crunchydata.com/blog/postgres-migration-pitstop-collations https://wiki.postgresql.org/wiki/Locale_data_changes The thing is some of the recommendations are not complete or/and not up-to-date. I see a lot of confusion in the field about this topic, because PostgreSQL users don't have the 'official recommendations' from the PostgreSQL community. So, my proposal to dedicate a chapter in the PostgreSQL documentation about the topic. best regards Alexey Shishkin
