samhza ed25116851 Assorted db changes (#333) ... * postgres: use transaction-scoped sql for upgrade * database: combine fixGuild and addGuild into getGuild * postgres, sqlite: simplify upgrade() * allow running commands in DMs without prefix this functionality was broken in 16095c0256 but is now fixed * allow running esmBot without a database Before this change, the only way to run esmBot without a database is to use the dummy database driver which is broken but fails silently. THis can lead to a confusing user experience. For instance, using `&command disable` with the dummy database driver will tell you that the command has been disabled even though it has not been. This change adds support for running esmBot with no database driver by leaving the DB= config option empty, and explicitly telling the user that some functionality is now unavailable rather than failing silently like the dummy driver. * remove dummy database driver		2022-12-12 11:15:10 -06:00
