Hmm, odd that it's causing a crash.
Which version of the oracle_fdw and which version of the oracle libraries are you linked to? Make sure to check 'ldd oracle_fdw.so'

---Then I took clues from https://github.com/dalibo/pg_qualstats/issues/1 and added oracle_fdw to shared_preload_libraries in postgresql.conf like this:shared_preload_libraries = 'oracle_fdw'but now I can't restart Postgres:---# service postgresql restart[....] Restarting PostgreSQL 9.4 database server: main[....] The PostgreSQL server failed to start.
