UPDATE:

with the idea to start my database with postgres 9.4 then dump the
databse. I run:

$ /usr/lib64/pgsql/postgresql-9.4/bin/pg_ctl -D /db/pgsql/data-9.4 start

but it returns this error:
FATAL: 58P01: could not access file "pg_stat_statements": No such
file or directory

$ ls -al data-9.4/pg_stat
.......
-rw------- 1 postgres postgres 905 Jul 9 15:36 pg_stat_statements.stat

Why do I have this error then ?
