Why I used a double pointer is to support the scenario like the following.
- There is no password requirement for Postgres, template1 and
maintenance db that is provided by the user.
- But there is a password requirement for user databases.
- If user doesn't provide the password during connection to
Maintenance database, later it prompts for
password while connecting to user database.
- Without the double pointer, further on for every database, it
prompts for the password and also
the case of --analyze-in-stages prompts for password for the all the stages.
