Not sure what you mean by "ghetto secaping" ... but doubling up a '
is the SQL standard escaping method, AFAIK.
If I just do:
SELECT 'can''t'::text;
I get "can't" which is what I'd expect. I would then expect
encode to escape the ' somehow. Even c-style escaping, like
"can\'t" would have been less surprising to me.
If there's something I'm missing, I'm still missing it.
