Panic - Format has changed

Hi,

last night we upgraded our primary web server, which included upgrading
postgres to 7.2.1

A rather unexpected change in behaviour has broken one of our
applications.

We have a column containing a varchar array. This used to be displayed
with all the elements quoted, seperated by commas i.e.
{ "a","b","c","d" }

Now, the quotes are only present if the element includes a quote or a
space. i.e.
{ a,"b b",c,d }

This is much more difficult to parse and will involve lots of code
changes in our application.  Is there ANY setting I can change that will
result in the data being displayed as before.
