After, um, briefly sleeping on this, I would like to go ahead with this. There is ongoing work to make ICU available globally, and as part of that I've also proposed a way to make the collation version tracking work on a database level. This here would be a useful piece on the overall picture. Independent of what becomes of the ICU effort, we could have glibc collation version tracking completely working for PG13. The only open question on this patch was whether it's a good version to use. I think based on subsequent discussions, there was the realization that this is the best we can do and better than nothing. In the patch, I would skip the configure test and just do #ifdef __GLIBC__ directly. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
