As Daniel already told you, it's pg_database.datlocprovider that matters.

"c" is NOT built-in. It's implemented thanks to the OS' libc as a dependency.
"b" is built-in, i.e. entirely within postgres, w/o external
dependencies (like icu or libc). New in PostgreSQL 18.

Given you're likely on "c", probably. As recommeded by Daniel. --DD
