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.
