There is nothing interesting in the Postgres logs at all to explain what 
is going on. I have ERROR statements when I try to drop a table that isn't 
there, but nothing when this COPY bugs out.

Yes, it seems to break with specific data. Particularly, it works with our 
COPY tests, but it doesn't work with the higher-level tests.

So, the situation is that I have a database writing interface that I wrote 
about six years ago, and we have been using a patched six-year-old 
Postgres JDBC driver for ages. I have just updated to the newest JDBC 
driver (which doesn't need to be patched for COPY), and I am now getting 
this error. Could the binary format have changed slightly? (I haven't 
changed my copy of Postgres when upgrading the JDBC driver - it is 8.4.4).

Thanks,

Matthew
