    NAME

    
    pg_upgradecluster - upgrade a new PostgreSQL cluster to a new major version.
     
    

    SYNOPSIS

    pg_upgradecluster [-v newversion] version name [data dir]  

    DESCRIPTION

    pg_upgradecluster upgrades an existing PostgreSQL server cluster (i. e. a collection of databases served by a postmaster instance) to a new version specified by newversion (default: latest available version). The configuration files of the old version are copied to the new cluster.

    The cluster of the old version will be configured to use a previously unused port since the upgraded one will use the original port. The old cluster is not automatically be removed. After upgrade, please verify that the new cluster indeed works as expected; if so, you should remove the old cluster with pg_dropcluster(8).  

    HOOK SCRIPTS

    Some PostgreSQL extensions like PostGIS need metadata in auxiliary tables which must not be upgraded from the old version, but rather initialized for the new version before copying the table data. For this purpose, extensions (as well as administrators, of course) can drop upgrade hook scripts into /etc/postgresql-common/pg_upgradecluster.d/
    . Scripts in that directory will be called with the following arguments:

    <old version> <cluster name> <new version> <phase>

    Phases:

    init
    A virgin cluster of version new version has been created, i. e. this new cluster will already have template1, but no user databases.
    finish
    All data from the old version cluster has been dumped/reloaded into the new one. The old cluster still exists.

    The scripts are called as the user who owns the database.
