This is really unpleasant situation since I intended to use binary
AND/OR operators with BIT(n) in SELECTs which as I know is not possible
with BYTEA type. So is there ANY way how use BIT(n) from Java even if it
will cause PostgereSQL specific and JDBC not compliant code (for example
using some PostgreSQL extensions or treating it as custom datatype or
whatever is possible) or should I definitely forget using BIT(n) from Java?
