Did you set the encoding with \encoding? I think it's critical for
determining line and field separators. If you only do SET
client_encoding, the backend will work but psql may not.
Or you mean that the first line of the text file is the whole file? In
that case I'd guess that the iconv procedure is borked somehow, or maybe
the input file is OK for everything except the linefeed(*)
(*) is "linefeed" plural or do you need to add an "s"? Is the singular
"linefood"???
