initdb: hint: You can change this by editing pg_hba.conf or using the option -A, or --auth-local and --auth-host, the next time you run initdb. | |
Success. You can now start the database server using: | |

Performing Upgrade | |

Analyzing all rows in the new cluster ok | |
Freezing all rows in the new cluster ok | |
Deleting files from new pg_xact ok | |
Copying old pg_xact to new server ok | |

Deleting files from new pg_multixact/members ok | |
Copying old pg_multixact/members to new server ok | |

Restoring global objects in the new cluster ok | |
Restoring database schemas in the new cluster | |
ok | |

Sync data directory to disk ok | |
Creating script to delete old cluster ok | |
Checking for extension updates notice | |
Your installation contains extensions that should be updated | |
with the ALTER EXTENSION command. The file | |
update_extensions.sql | |
when executed by psql by the database superuser will update | |
these extensions. | |
Upgrade Complete | |
---------------- | |
Optimizer statistics are not transferred by pg_upgrade. | |
Once you start the new server, consider running: | |
/usr/pgsql-16/bin/vacuumdb -U postgres --all --analyze-in-stages | |
Running this script will delete the old cluster's data files: | |
./delete_old_cluster.sh | |
[postgres@posvt01 ~]$ psql -f update_extensions.sql | |
[postgres@posvt01 ~]$ /usr/pgsql-16/bin/vacuumdb -U postgres --all --analyze-in-stages |
