Actually it's a vfs supporting compressing databases dynamically and I wanted to test it with some external data. But it looks like I either can take some other general db and convert it to this vfs format as a whole (without sqlite api, just by file converting) or populate it with manual queries. This is because attaching general db in this case won't work right from the box. Although it is still possible for my vfs to recognize that the newly attached db has a different format and bypass some calls, this will require extra work and testing.
