Have you tried clearing /var/lib/pgsql/13/data and doing the init over again? If you do try it monitor the output carefully. here’s the complete process: bash-4.4$ /usr/pgsql-13/bin/initdb -D /var/lib/pgsql/13/data/ --locale=en_US.UTF-8 The files belonging to this database system will be owned by user "postgres". This user must also own the server process. The database cluster will be initialized with locale "en_US.UTF-8". The default database encoding has accordingly been set to "UTF8". The default text search configuration will be set to "english". Data page checksums are disabled. fixing permissions on existing directory /var/lib/pgsql/13/data ... ok creating subdirectories ... ok selecting dynamic shared memory implementation ... posix selecting default max_connections ... 100 selecting default shared_buffers ... 128MB selecting default time zone ...

Success.
