The dollar quoting appears to have fixed it; thank you. I apologize for my
folly in sending out the original message.

Do you want to remove the double quotes around the word or the
apostrophe between y and s? Regardless, you might want to look at the
regexp_replace or translate functions:

Sounds like a problem with how you're handling your data in your
middleware, as this shouldn't be a problem regardless of the
characters in the string if you're handling things correctly. If you
post an example perhaps people can offer suggestions on how you can
handle things more safely. Are you interpolating variables directly
into SQL statements? If so, don't do that: use bind variables instead.

You could use dollar quotes, but it sounds like your problem might be
able to be solved using bind variables.
