Facing issues with pgsql upgrade.

Hello All,

I'm facing the following issue while upgrading pgsql 9.6 to pgsql 13. 

It's saying database "template0" "template1" does not exist on source 9.6, please advise.

[postgres@htf:/var/lib/pgsql]$ psql

psql (9.2.24, server 9.6.24)

WARNING: psql version 9.2, server version 9.6.

         Some psql features might not work.

Type "help" for help.

postgres=# \c template0

FATAL:  database "template0" does not exist

DETAIL:  The database subdirectory "base/13268" is missing.

Previous connection kept

postgres=# \c template1
