Thanks for the reply Tom, however I don't think you understand my issue.
I'm not using addslashes and I am using the SQL standard way to
escape a single quote. The problem is that I want to put a literal \'
inside the database. So if \ is no longer an escape character, and ''
is the SQL way to pass a literal ' then you would think that \'' would
put a literal \' into the database, however postgres rejects this and
spits out an error.

So the question isn't how to I escape ', the question is how do I insert
a literal \' into a varchar?

Thanks,
