I've just realised I've been doing this a stupid way without thinking
about it. Unsurprisingly it turns out that no Java/JDBC snippets are
required. The much, much easier way to find the error code:

$ psql

... blah blah blah ...

test=# \set VERBOSITY verbose
test=# select currval('test_seq');
ERROR: 55000: currval of sequence "test_seq" is not yet defined in this
session
LOCATION: currval_oid, sequence.c:644

In retrospect it seems kind of obvious - "surely psql must have way to
show this information, maybe I should look at the manual....".
