PostgreSQL 9.4 is not a supported version, and 9.4.1 is missing over 5
years worth of bugfixes that happened while it *was* supported.

oid 2610 means pg_index. Being unable to open that means your database
is corrupt on disk. I would suggest you look into restoring the latest
backup.

You may be able to do partial recovery if you try a startup without
system indexes and immediately dump the database and reload it into a
new cluster, but going to your backups will most likely be the safer
and better choice.
