Re: postgres 7.2.1 parse bug

Was the "new behavior" introduced in 7.2 or 7.2.1? For
me it seems effective 7.2.1. 7.2 seems to go with the
old one. So in 7.2:.
insert into testa values ('{"bob"
,"moo",ab"x"yz,"","theend"}');

produces x as the third array element and its in 7.2.1
its abxyz.

Thanks..
