Exclude certain application pgaudit logging?

Currently, we use Object audit logging to capture all READ access to
columns FOO_1, FOO_2 and FOO_3 in table BAR.SCRABBLE. (They are the three
columns have PII data.)

The problem is that the application legitimately reads these columns
thousands of times per day. Thus, the log fills up with meaningless data
that swamps any legitimate invalid accesses.

Thus, I'd like to exclude reads from "Postgresql JDBC Driver". (Currently,
I filter that out using "grep -v" in a shell script that runs hourly from
cron, but I find that unsatisfactory.)
