Thank you both for the quick replies and the links.

What I still do not understand (I'm a little slow) is the fact that pgadmin3
showed the data as E'string'. So I'm wondering if the data is now different
in the sense that I need use the 'E' in the field.

For example I have the last name of O'Reilly
the field lname now appears to contain E'O'Reilly'

So will the normal select statements work;

Select * from table where lname = 'O'' Reilly'
Select * from table where lname like 'O%'

or will I need to know the data contains the "E" and add the 'E' to the sql
statements?

Thanks
Johnf
