If you select to dump the schema and analyze it, the tool will print the above
section. This summarizes the number and type of objects in the database. It is
generated by running C<mysqldump --no-data>, not by querying the
INFORMATION_SCHEMA, which can freeze a busy server. You can use the
L<"--databases"> option to specify which databases to examine. If you do not,
and you run the tool interactively, it will prompt you as shown.
You can choose not to dump the schema, to dump all of the databases, or to dump
only a single named one, by specifying the appropriate options. In the example
above, we are dumping all databases.
If you specify L<"--databases"> or L<"--all-databases">, the tool will print
the above section. This summarizes the number and type of objects in the
