61 dbupgrade2_tool.pl [options]
63 A validation and information tool for the database upgrade scripts
64 in \'sql/Pg-upgrade2\'.
66 At startup dbupgrade2_tool.pl will always check the consistency
67 of all database upgrade scripts (e.g. circular references, invalid
68 formats, missing meta information). You can but don\'t have to specifiy
72 --list Lists all database upgrade tags
73 --tree Lists all database upgrades in tree form
74 --rtree Lists all database upgrades in reverse tree form
75 --graphviz[=file] Create a Postscript document showing a tree of
76 all database upgrades and their dependencies.
77 If no file name is given then the output is
78 written to \'db_dependencies.png\'.
79 --format=... Format for the graphviz output. Defaults to
80 \'png\'. All values that the command \'dot\' accepts
81 for it\'s option \'-T\' are acceptable.
82 --nodeps List all database upgrades that no other upgrade
84 --create=tag Creates a new upgrade with the supplied tag. This
85 action accepts several optional other options. See
86 the option section for those. After creating the
87 upgrade file your \$EDITOR will be called with it.
88 --apply=tag Applies the database upgrades \'tag\' and all
89 upgrades it depends on. If \'--apply\' is used
90 then the option \'--user\' must be used as well.
91 --applied List the applied database upgrades for the
92 database that the user given with \'--user\' uses.
93 --unapplied List the database upgrades that haven\'t been applied
94 yet to the database that the user given with
96 --test-utf8 Tests a PostgreSQL cluster for proper UTF-8 support.
97 You have to specify the database to test with the
98 parameters --dbname, --dbhost, --dbport, --dbuser
100 --help Show this help and exit.
103 --client=id-or-name The name (or database ID) of the client to use for
104 database connectivity. You must provide both a client
106 --user=name The name of the user configuration to use for
107 database connectivity. You must provide both a client
109 --auth-db Work on the authentication database instead of a
111 --dbname=name Database connection options for the UTF-8
112 --dbhost=host handling test.
117 Options for --create:
118 --type \'sql\' or \'pl\'. Defaults to sql.
119 --description The description field of the generated upgrade.
120 --depends Tags of upgrades which this upgrade depends upon.
121 Defaults to the latest stable release upgrade.
122 Multiple values possible.
