dbupgrade2_tool.pl [options]
A validation and information tool for the database upgrade scripts
- in 'sql/Pg-upgrade2'.
+ 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
+ formats, missing meta information). You can but don\'t have to specifiy
additional actions.
Actions:
--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'.
+ written to \'db_dependencies.png\'.
+ --format=... Format for the graphviz output. Defaults to
+ \'png\'. All values that the command \'dot\' accepts
+ for it\'s option \'-T\' are acceptable.
--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.
+ --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.
+ --applied List the applied database upgrades for the
+ database that the user given with \'--user\' uses.
+ --test-utf8 Tests a PostgreSQL cluster for proper UTF-8 support.
+ You have to specify the database to test with the
+ parameters --dbname, --dbhost, --dbport, --dbuser
+ and --dbpassword.
--help Show this help and exit.
Options:
--user=name The name of the user configuration to use for
database connectivity.
-END_HELP
- ;
+ --dbname=name Database connection options for the UTF-8
+ --dbhost=host handling test.
+ --dbport=port
+ --dbuser=user
+ --dbpassword=pw
