Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.
Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

## Python/Regex fix
This is a reminder for me or a task if anyone wants :P
Basically, The last two questions aren't really regex's questions.

Hello Philip!
I think there is an issue with this part of the code of rqlite (store/store.go).

s.mu.Lock()
defer s.mu.Unlock()

As now I can use the files by opening the Schema Compare from the context-menu on the connection, and then click Open .scmp-file.
If I try to open the file from the file explorer or the project explorer I only get the underlaying XML-file, which mostly often isn't very useful.
It would be great to op
