Uh...we also met duplicate rows with primary key column through restoring database by pg_basebackup.
HAAAA.........................
I don't think its an issue with primary key index corruption.

Then updating:
/usr/pgsql-9.5/bin/pg_upgrade -b /usr/pgsql-9.4/bin/ -d /data/upgrade/94 -B /usr/pgsql-9.5/bin/ -D /data/upgrade/95 -k
and so on to 9.6
The original 9.4 database has the same encoding setup?
FYI, you can use pg_upgrade to go straight from 9.4 to 9.6.
https://www.postgresql.org/docs/9.6/static/pgupgrade.html
"pg_upgrade supports upgrades from 8.4.X and later to the current major release of PostgreSQL, including snapshot and alpha releases."--
after that server starts normally.
