SQL Prompt includes a feature to exclude specific databases – in this case, the master database – we would expect this functionality to reliably prevent any interaction with the excluded databases during code suggestions or IntelliSense operations. The current behavior suggests that the exclusion option may not be functioning as intended.

We expect that when an exclusion is defined, no connection attempt should be made to the excluded database. This would allow all other user databases to be loaded, even if with limited functionality.
