I wouldn’t trust Finder here (see for example Michael Tsai - Blog - Finder Shows Incorrect Folder Sizes or the much older thread here File size in finder ' get info' does not … - Apple Community).
Just tried it with one of my databases:
- Finder says 685,9 MB
- command line says 645 MB
That’s a difference of about 6 percent.
du -h on the command line should be more reliable. Also, where do you see a Trash folder inside a database package? I checked here and couldn’t find one. And when I deleted a file, it wasn’t moved to any special location in the database package either, it just stayed in Files.noindex...
