pg_escape with copy

I have data that I'm running through pg_escape_sting in php and then adding to stdin for a copy command. The problem is "O'reilly" is being changed to "O''Reilly" in the string and then in the db. I saw with the copy command I can specify the escape but it isn't working for me. Should this command fix this double 'single' quote issue when I put it in the db? And what is the proper syntax? COPY mytable FROM stdin with escape Thanks!
