no quotes in arrays in 7.2

I upgraded to pg 7.2.
When I do a SELECT on a column defined as text[ ] I get:

{{FLTL,DFBV2bI16nfqCEag,1000}}

when I do the same SELECT on postgres 7.1 I get the same result but with
quotes:

{{"FLTL","DFBV2bI16nfqCEag","1000"}}

Only using a comma as a separator is not very good, because the text in the
array can contain commas, so seperating can get impossible.
Is the new output a bug?
