sqlite_zstd_vfs

I've never done it, but for the readonly case, I think all you need to is to combine the existing reader VFS with zstd-seekable-format-go. https://github.com/ncruces/go-sqlite3/discussions/117#discus... For read/write, I'm honestly not sure. The Zipvfs is an… erm… architectural mess that only really works because it accesses private SQLite APIs. Which is fine, but history has shown the SQLite team is willing to break those APIs, as they did for the ones they build the SQLite encryption extension on. https://sqlite.org/zipvfs/doc/trunk/www/howitworks.wiki The zstandard alternative is sqlite_zstd_vfs, which faces the same architectural issues. So, I'd rather not go there. But should be doable, as long as you're not needing private APIs. https://github.com/mlin/sqlite_zstd_vfs
