F27 to F28 - Postgresql upgrade fails

[Clifford Snow]

I just upgraded from Fedora 27 to 28. Everything working except the upgrade
from Postgresql 9.6 to 10

Searching for help led me to manually add postgis-2.3.so and
rtpostgis-2.3.so to /usr/lib64/pgsql/ and
/usr/lib64/pgsql/postgresql-9.6/lib/

Then when postgresql-setup --upgrade is run a fatal error is reported for
missing libraries.
the file loadable_libraries.txt contains

could not load library "$libdir/postgis-2.3": ERROR:  could not load
library "/usr/lib64/pgsql/postgis-2.3.so": /usr/lib64/pgsql/postgis-2.3.so:

mbol: DatumGetFloat8
could not load library "$libdir/address_standardizer-2.3": ERROR:  could
not access file "$libdir/address_standardizer-2.3": No such file or
directory


Any suggestions to solve this without having to manually restore from my
dump?

Thanks in advance,
Clifford
