The problem was a combination of 2 mis-matched data types. Consider this test case: ----------------begin------------------- drop table if exists bar; drop table if exists foo; create table foo ( system_id smallint, credibility real not null ); insert into foo ( system_id, credibility) values (1,1); copy foo to '/tmp/repeat.dat' with binary; create table bar ( system_id int, credibility numeric(10,9) not null ); copy bar from '/tmp/repeat.dat' with binary; copy bar from '/var/lib/pgsql/backups/repeat.dat' with binary; psql:repeat:19: ERROR: insufficient data left in message CONTEXT: COPY bar, line 1, column system_id --------------end----------------- It's interesting to note that I get this error only when there are 2 bad fields. If I fix only the numeric field, I get "incorrect binary data format" on the int field. If I fix only the smallint field, I get "invalid length in external "numeric" value on the real field. So, my fault, and the fix is obvious. But it does seem like a less than ideal error message. Also, maybe a sentence like this would be helpful on the COPY page: "Be careful that the data types match from 'copy to' to 'copy from'. There is no implicit conversion done in binary mode..." or some such?
