I don't know what JAVA brings to the mix, but the argument to currval
is a string. Before version 8 you would do something like:
SELECT currval('taddress_addressid_seq')
This string isn't guaranteed to work, but would normally be the correct
one. In 8.0 there is a function that will return the sequence name.
Note that you must have also done a nextval or setval call on that
sequence in the current session or the value is undefined and trying to
access it will result in an error.
