No, no directly

there are no hash array

there is a workaround a hstore module

Why hstore is a workaround ? hstore is a proven and
mature module.
And since 9.0 is has a lot of improvements and
make the life easy in some cases today and here.

attention - it doesn't allow a nested values

for more complex values is other was - using a temp tables - you can
fill a temp table and in next step a plpgsql code use this temp table.
But it should have a performance impacts.
