No; you could easily be breaking existing queries, for example
Let me jump in for half a second here (no pun intended), but what about the use of back quotes? ` `? Use a very limited escaping policy of \` => ` and \\ => \ . Back quotes aren't used in any SQL or PL/PgSQL that I'm aware of. I know ruby, perl, and sh make use of back ticks, but for all intents and purposes, pl/perl shouldn't use back ticks, and if it is, for performance reasons a DBA shouldn't. Use of open() or system() should be encouraged as it is possible to avoid fork()/exec()'ing a shell, nevermind that ``'s aren't the wisest inclusions for DBAs. If ``'s are needed in the pl language, they can be nominally included with a \`\`, but given their relative rareness compared to ' or ", I'd think the addition of ` would be welcome and much less cumbersome/easier to remember than other options that have popped up in this thread.
