Upgrading from v12.7 to v15.7

Hello Engineers,
After upgrading from v12.7 to v15.7, I ran the following command and got
this error message.

postgres_upgrade_work_area]$ /usr/pgsql-15/bin/pg_upgrade \
> --check \
--old-datadir=/data/postgres12 \

Your installation references loadable libraries that are missing from the

new installation. You can add these libraries to the new installation,
or remove the functions using them from the old installation. A list of
problem libraries is in the file:

/data/postgres/pg_upgrade_output.d/20240708T141557.291/loadable_libraries.txt

Does anyone know where I can download rpm cstore_fdw and oracle_fdw. I have
searched and can't find the rpm for v15.7.

I will greatly appreciate any help.
