Thanks for the update, 
you are correct, /12950 is not available in /var/lib/pgsql/9.3/data/base also I do not have the database server or DB backup to restore it.
do I need to create new Postgres DB to resolve it or I need to follow any other step?

FYI, due to a space issue on default (/var/lib/pgsql/9.3) location of DB, I had tried to change data directory location of PostgreSQL and followed below step to change location but to verify data directory location I need to log in by user (postgres) to run (show data_directory) which is not possible due to original error posted in request 😞

1.       Step : stope postgresql service $ sudo systemctl stop postgresql-9.3 and verify by command sudo systemctl status postgresql-9.3

2.       Created new directory/ location for db data ($ sudo mkdir postgresql)

3.       Sudo chown postgres:postgres postgresql

4.       Then copy all data by command (sudo rsync -av /var/lib/pgsql/9.3/data /opt/postgresql/)

5.       Login with (sudo –u postgres –i) on server

  1. Open (vim /opt/postgresql/data/postgresql.conf)
  2. Connented out (#data_directory = 'ConfigDir')
  3. Added new line below above line (data_directory = '/opt/postgresql/data')

6.       Updated (sudo vim /usr/lib/systemd/system/postgresql-9.3.service) by adding (Environment=PGDATA=/opt/postgresql/data) line below line and commented line (#Environment=PGDATA=/var/lib/pgsql/9.3/data/) 7. unable to run show data_directory to verify data directory location due to below error same error 


psql: FATAL:  database "postgres" does not exist
DETAIL:  The database subdirectory "base/12950" is missing.

I think you missed postgres database directory. Can you check using a
file manager if the directory "base/12950" exists in your PGDATA?

If it is lost the only way is to restore your instance from a backup.
