    NAME

    
    pg_maintenance - perform maintenance tasks on all clusters
     
    

    SYNOPSIS

    pg_maintenance [-f|--full] [-a|--analyze] [-v|--verbose] [--force]  

    DESCRIPTION

    This script performs maintenance actions on all databases in all clusters. In particular, this calls vacuumdb on all databases, which frees up unused space and helps to improve database performance (if --analyze is specified).

    This script is intended to be called regularly in a cronjob.  

    OPTIONS

    -c, --cluster version/cluster
    Perform maintenance only on specified cluster. By default, all clusters are handled.
    -f, --full
    Perform a ``full vacuum'', which is more effective but takes more time and needs to completely lock tables while working on it.
    -a, --analyze
    Perform some statistical analyses on the tables which helps to improve database performance. This only needs read access to the tables, thus does not require any locking.
    -v, --verbose
    Passed to vacuumdb, which prints lots of information about the vacuuming and analysis.
    --force
    By default a cluster is not processed if autovacuuming is enabled for it. If this option is specified, the cluster is processed regardless of the autovacuum daemon status.
