- CAPTCHA: removed the extra slash

More backup stuff

- Made some things nicer for some of the DBs
- Made postgreSQL work on non empty databases
- Made SQLite ultra fast on restore

- Properly escaped (as far as I know) the profile data fields so that one may now use reserved words as column names
