If you did start the new cluster, it's composed to shared information and it truly is unsafe to use the outdated cluster. The outdated cluster will have to be restored from backup In such a case.
Install the identical extension shared object information on The brand new standbys that you just installed in The brand new Main cluster.
of course, no one ought to be accessing the clusters in the update. pg_upgrade defaults to working servers on port 50432 in order to avoid unintended consumer connections.
The --Positions choice will allow several CPU cores to be used for copying/linking of data files and to dump and restore databases schemas in parallel; website an excellent location to begin is the maximum of the quantity of CPU cores and tablespaces.
(Tablespaces and pg_wal can be on distinct file programs.) Clone manner offers the same velocity and disk space positive aspects but would not result in the aged cluster for being unusable as soon as the new cluster is began.

You can also specify user and port values, and no matter whether you'd like the data documents linked or cloned in lieu of the default copy actions.
generally speaking it really is unsafe to accessibility tables referenced in rebuild scripts until eventually the rebuild scripts have run to completion; doing so could produce incorrect outcomes or weak performance. Tables not referenced in rebuild scripts might be accessed straight away.
If an error happens while restoring the database schema, pg_upgrade will exit and you will have to revert for the aged cluster as outlined in stage 17 down below. to test pg_upgrade once more, you have got to modify the old cluster Therefore the pg_upgrade schema restore succeeds.
confirm the “most recent checkpoint spot” values match in all clusters. Also, ensure wal_level will not be established to minimum in the postgresql.conf file on The brand new Main cluster.
Once you are satisfied with the enhance, you may delete the aged cluster's knowledge directories by functioning the script outlined when pg_upgrade completes.
For resource installs, if you wish to put in the new server inside of a personalized locale, use the prefix variable:
For Windows end users, you have to be logged into an administrative account, and then start a shell as being the postgres user and set the proper route:
