Adding an extra apostrophe is one of the ways you can escape another apostrophe with Postgre. I believe Postgre can use an extra apostrophe or a backslash... and the API call you're using just happens to elect using the extra apostrophe over the backslash. If you look at the data inserted into the database is there only one apostrophe in your data? If so, that's what it is. If there's two it could be as the previous poster said and magic quotes is enabled.
