+dbupgrade2_tool.pl [options]
+
+ A validation and information tool for the database upgrade scripts
+ in 'sql/Pg-upgrade2'.
+
+ At startup dbupgrade2_tool.pl will always check the consistency
+ of all database upgrade scripts (e.g. circular references, invalid
+ formats, missing meta information). You can but don't have to specifiy
+ additional actions.
+
+ Actions:
+ --list Lists all database upgrade tags
+ --tree Lists all database upgrades in tree form
+ --rtree Lists all database upgrades in reverse tree form
+ --graphviz[=file] Create a Postscript document showing a tree of
+ all database upgrades and their dependencies.
+ If no file name is given then the output is
+ written to 'db_dependencies.ps'.
+ --nodeps List all database upgrades that no other upgrade
+ depends on
+ --apply=tag Applies the database upgrades 'tag' and all
+ upgrades it depends on. If '--apply' is used
+ then the option '--user' must be used as well.
+ --help Show this help and exit.
+
+ Options:
+ --user=name The name of the user configuration to use for
+ database connectivity.
