No, no directly

there are no hash array

there is a workaround a hstore module

http://www.postgresql.org/docs/9.0/static/hstore.html

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.
