As I understand it, you can't represent a \0 byte in a text/varchar
constant; this seems to be due to the way the backend internally
represents these types. I always get horribly confused in this area
since these representations are encoding-dependent, though.. You should
be able to represent it ok in a bytea constant (but then of course you
need a bytea field to store it in..)

If you were using PreparedStatement.setString() to set a String
parameter containing an embedded \0, recent drivers should have thrown
an IllegalArgumentException well before the query hit the backend. I'm
interested to know exactly how you managed to get a \0 into the query --
were you constructing the whole INSERT string yourself rather than using
PreparedStatement parameters? I don't think the queries themselves are
checked, from memory.
