It is *extremely* dangerous. But neither more nor less dangerous than
any interface that allows you to submit SQL directly to the server.
The \e command merely offers an alternative to the command-line editing
to craft your SQL statements and is very convenient when you are editing
a long statement. When done, you exit and the command is submitted just
as it is submitted when you press <Enter> at the command-line.
If you change your mind while in the editor, just clear the text in the
editor and exit. Nothing will be run.
Cheers,
Steve
