Virtual tables are fully supported by my CGO free driver: https://pkg.go.dev/github.com/ncruces/go-sqlite3

You can have a look at a bunch of examples in my extensions folder: https://github.com/ncruces/go-sqlite3/tree/main/ext

PS: The mattn CGO driver actually doesn't seem to support wrapping the xBegin/xSync/xRollback/xCommit methods. Mine actually does, although it's largely untested, as I haven't needed this yet.
