Even if PG supports two versions of ICU, how does someone actually go about removing every dependency on the old
versionand replacing it with the new? Can it be done without downtime? Can it be done without modifying a running
application?Avoiding “collate” clauses on SQL statements requires working behind the scenes with defaults and indexes
andpartitions and constraints and everything else. I’m having a hard time coming up with a way this would be possible
inpractice, with all the places collations can show up.
Is the idea of “alter database” to change the default collation even realistic?
I’m having a bit of trouble picturing what the end game is here
