Using a grave accent to quote a column or table name is a mysql-ism.
It only works in MySQL (and also in SQLite because SQLite tries to be
compatible with everybody). The SQL standard notation is double-quote:
SELECT "sql" FROM "sqlite_master" WHERE "name" = 'Mail';

Yes, it works as intended. The IF NOT EXISTS has already been
processed and found to be true before the text is inserted into the
sqlite_master table, so why keep it around?
