WARNING: The configuration files were replaced by default configuration.
WARNING: The previous configuration and data are stored in folder
WARNING: /var/lib/pgsql/data-old.
WARNING: If you've just upgraded your database from a previous major version of
Fedora or RHEL, please run reindexdb against your databases.  Core library
collation data may have changed and this will invalidate database indexes.  For
example, in Fedora 28 and RHEL 8 there have been extensive changes in glibc
collations to support ISO 14651:2016 (Unicode 9.0.0 data) and your indexes may
be affected: https://sourceware.org/ml/libc-announce/2018/msg00002.html
