change deprecated parameter pw and db - 2nd try

[ziegenberg]

SUMMARY

Parameters db and passwd are deprecated, using database and password is recommended by the DB-API 2.0.

This MySQL collections support two connectors:

• PyMySQL
• MySQLdb aka mysqlclient

In PyMySQL the change from the short parameter to the new long-form was made with v0.6.7 (and the short forms are kept as an alias for database and password). Warnings will be activated around 2022 (for details, see PyMySQL/PyMySQL#939).

In MySQLdb the change was introduced with v1.3.8 (and the short forms are kept as an alias for database and password).
