It's not clear to me whether your error is during COPY or afterwards. If it is during COPY, edit your textfile and assign unique values to each row. If it is afterwards, use SELECT setval('sequence_name', SELECT max(serial_field) FROM table); to set the sequence value. (You probably have to be running 7.1 to use a sub-select like that.) -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight http://www.lfix.co.uk/oliver PGP: 1024R/32B8FAA1: 97 EA 1D 47 72 3F 28 47 6B 7E 39 CC 56 E4 C1 47 GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "For I am persuaded, that neither death, nor life, nor angels, nor principalities,nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature,shall be able to separate us from the love of God, which is in Christ Jesus our Lord."
