       error: glibc version changed: baseline is glibc-2.40-66, postgresql_15 has glibc-2.42-84. Checked
       glibc version, not actual collation data, as a proxy for collation drift.
       This can change collation versions and require a reindex.
       If this bump has been reviewed for collation safety, update the baseline in nix/checks.nix to match.
