PostgreSQL

  This option is only available for servers running PostgreSQL 9.6 and later.
  ====
[.term]#`+-e+` +
#[.term]#`+--echo+`#::
  Echo the commands that vacuumdb generates and sends to the server.
[.term]#`+-f+` +
#[.term]#`+--full+`#::
  Perform [.quote]#“[.quote]#full#”# vacuuming.
[.term]#`+-F+` +
#[.term]#`+--freeze+`#::
  Aggressively [.quote]#“[.quote]#freeze#”# tuples.
[.term]#`+-j +`_`+njobs+`_ +
#[.term]#`+--jobs=+`_`+njobs+`_#::
  Execute the vacuum or analyze commands in parallel by running _`+njobs+`_ commands simultaneously. This option reduces the time of the processing but it also increases the load on the database server.
  +
  vacuumdb will open _`+njobs+`_ connections to the database, so make sure your link:runtime-config-connection.html#GUC-MAX-CONNECTIONS[max_connections] setting is high enough to accommodate all connections.
  +
  Note that using this mode together with the `+-f+` (`+FULL+`) option might cause deadlock failures if certain system catalogs are processed in parallel.
[.term]#`+--min-mxid-age +`_`+mxid_age+`_#::
  Only execute the vacuum or analyze commands on tables with a multixact ID age of at least _`+mxid_age+`_. This setting is useful for prioritizing tables to process to prevent multixact ID wraparound (see link:routine-vacuuming.html#VACUUM-FOR-MULTIXACT-WRAPAROUND[Section 24.1.5.1]).
  +
  For the purposes of this option, the multixact ID age of a relation is the greatest of the ages of the main relation and its associated TOAST table, if one exists. Since the commands issued by vacuumdb will also process the TOAST table for the relation if necessary, it does not need to be considered separately.

[.term]#`+--min-xid-age +`_`+xid_age+`_#::
  Only execute the vacuum or analyze commands on tables with a transaction ID age of at least _`+xid_age+`_. This setting is useful for prioritizing tables to process to prevent transaction ID wraparound (see link:routine-vacuuming.html#VACUUM-FOR-WRAPAROUND[Section 24.1.5]).

[.term]#`+-q+` +
#[.term]#`+--quiet+`#::
  Do not display progress messages.
[.term]#`+--skip-locked+`#::
  Skip relations that cannot be immediately locked for processing.

  This option is only available for servers running PostgreSQL 12 and later.

[.term]#`+-t +`_`+table+`_`+ [ (+`_`+column+`_`+ [,...]) ]+` +
#[.term]#`+--table=+`_`+table+`_`+ [ (+`_`+column+`_`+ [,...]) ]+`#::
  Clean or analyze _`+table+`_ only. Column names can be specified only in conjunction with the `+--analyze+` or `+--analyze-only+` options. Multiple tables can be vacuumed by writing multiple `+-t+` switches.
  +
  [TIP]
  ====
  ==== Tip

  If you specify columns, you probably have to escape the parentheses from the shell. (See examples below.)
  ====
[.term]#`+-v+` +
#[.term]#`+--verbose+`#::
  Print detailed information during processing.
[.term]#`+-V+` +
#[.term]#`+--version+`#::
  Print the vacuumdb version and exit.
[.term]#`+-z+` +
#[.term]#`+--analyze+`#::
  Also calculate statistics for use by the optimizer.
[.term]#`+-Z+` +
#[.term]#`+--analyze-only+`#::
  Only calculate statistics for use by the optimizer (no vacuum).
[.term]#`+--analyze-in-stages+`#::
  Only calculate statistics for use by the optimizer (no vacuum), like `+--analyze-only+`. Run several (currently three) stages of analyze with different configuration settings, to produce usable statistics faster.
  +
  This option is useful to analyze a database that was newly populated from a restored dump or by `+pg_upgrade+`. This option will try to create some statistics as fast as possible, to make the database usable, and then produce full statistics in the subsequent stages.
[.term]#`+-?+` +
#[.term]#`+--help+`#::
  Show help about vacuumdb command line arguments, and exit.
