BUG #15799: Create extension postgres_fdw failed

create extension postgres_fdw;
ERROR: could not load library "/usr/pgsql-10/lib/postgres_fdw.so":

This looks like a version mismatch problem --- your postgres_fdw is newer
than your server (possibly just a minor release newer, but still newer).

It's unfortunate that the error message isn't more on-point, but we don't
have enough control over the dynamic linker to make it so.

Thank you. I bounced the server second time and it worked
