REFRESH MATERIALIZED VIEW error

Greetings,

After an OS upgrade from CentOS 7 to RHEL 9.2, our Materialized Views are not getting refreshed. We are receiving this error:

From log...
2023-10-04 00:04:01.885 EDT [235717] ERROR: could not access file "$libdir/file_fdw": No such file or directory
2023-10-04 00:04:01.885 EDT [235717] CONTEXT: SQL statement "REFRESH MATERIALIZED VIEW xxxxxx_vw with data" PL/pgSQL function refresh_xxxxxx_mvw() line 3 at SQL statement

From console...
dbname=> REFRESH MATERIALIZED VIEW xxxxxx_vw;
ERROR: could not access file "$libdir/file_fdw": No such file or directory

There is a file_fdw in the database...

dbname=> select * from pg_foreign_data_wrapper;

oid | fdwname | fdwowner | fdwhandler | fdwvalidator | fdwacl | fdwoptions
-------+----------+----------+------------+--------------+--------+------------
16399 | file_fdw | 10 | 16397 | 16398 | |
(1 row)

But none in $libdir:

bash-5.1$ /usr/pgsql-12/bin/pg_config --libdir
/usr/pgsql-12/lib
bash-5.1$ cd /usr/pgsql-12/lib
bash-5.1$ ls -la file_fdw
ls: cannot access 'file_fdw': No such file or directory

We recreated the Materialized view but was still not able to refresh the Materialized View - Same Error.

How did the OS upgrade change the way the REFRESH MATERIALIZED VIEW executed, and how do we get the statement to find file_fdw?

TIA, Bob
