You are most welcome.
A small warning:
```sh
warning: assigning to 'char *' from 'const char *' discards qualifiers
[-Wincompatible-pointer-types-discards-qualifiers]
pRet->zWalName2 = &zWalName[sqlite3Strlen30(zWalName)+1];
```
If I create a new database, the sqlite will try access journal first, then create journal file. After I set journal_mode = WAL2, sqlite delete + journal and create 2 WAL file.
Is there a way to let sqlite skip create journal file when I intend to use WAL ? (a flags pass to sqlite3_open_v2 to avoid call "pargama journal_mode = WAL" late)
The is VFS only SQLITE_OPEN_WAL, maybe reuse it to do the work(only for create new database).
