CentOS 7 is glibc 2.17
AlmaLinux 8 is glibc 2.28
There are known issues with glibc upgrades (in particular 2.28, but also
in general) causing collation changes which break all indexes which use
glibc collations (basically text, varchar, char). You need to rebuild
them, preferably before allowing *any* write activity (inserts or updates).
