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

You didn't install the file_fdw.so library that underlies the file_fdw
extension.

Thank you Tom! We downloaded the file_fdw.so library and recompiled the Materialized views and the application is
runningnormally.
Thank you for your insight!
Bob
