This is documented behavior for arrays:
http://developer.postgresql.org/docs/postgres/arrays.html#AEN5764
and has been that way for a very long time. If we change it we will
break every array-using application on the planet, because it will
in fact be impossible to parse an array value unambiguously.

I don't think "one user was confused" justifies fooling with this.
