Enable hash partitioning of text arrays
hash_array_extended() needs to pass PG_GET_COLLATION() to the hash
function of the element type. Otherwise, the hash function of a
collation-aware data type such as text will error out, since the
introduction of nondeterministic collation made hash functions require
a collation, too.
The consequence of this is that before this change, hash partitioning
using an array over text in the partition key would not work.
