Something that includes "'" would be clearest. I thought of <' and '>,
but this would break:
if var <'yes'

I think {' and '} might work.  Arrays are specified as '{val, val}',
which is safe because it is opposite of the suggested syntax.  I can't
think of any case where you would use an opening brace, then a single
quote.  Interestingly, it looks like a C braces:
CREATE FUNCTION test() ...{'    x = 'no';'}

Of course, this brings up a problem.  What if we do:

CREATE FUNCTION test() ...{'    x = '}text';'}

Oops, two closing mega-quotes.

One clean way would be to use {' to start a quote, and }' to end it, so
we have:

CREATE FUNCTION test() ...{'    x = 'text';}'

which looks even better and this is safe because both braces in '}text}'
are seen in a quoted string:
CREATE FUNCTION test() ...{'    x = '}text}';}'

Also, I can't imagine anyone defining those as operators.
