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.
