pgsql 7.4.1 copy - end-of-copy marker corrupt - Mailing list pgsql-general

I just upgraded to 7.4.1.  I was loading my database using 'copy'.  Some
tables loaded with no problem, while some gave me the error:
===
 ERROR:  end-of-copy marker corrupt
CONTEXT:  COPY author, line 49: "49\aoD{\BABABABABARENG
\t5p.\19840426"
===

This is the load script:
===
\set AUTOCOMMIT off
COPY author FROM '/tmp/author.data' USING DELIMITERS '\\';
commit;

and this is the line in the data file it complains:
===
49\aoD{\BABABABABARENG
\t5p.\19840426\.XfqWM+Ke,8+Ae-9PWPn)}#6eVa_QuNi*%{Y[?ip]Gx]6i-H[W&8K$dp/}uk57Dl6].*IdV 5(Lxl?4bS5~yhyY18(WcoZ

pz~*!CXKb-9xLN7%eDWqzN7=]{lt1ssbG$HB^0hblc}(pvvFyDv

I think this is strange since I've loaded the tables with the same
datafile and same command (except for the autocommit part) in 7.3.3 with
no problem.  Even in 7.4.1, I have some tables loaded successfully.

Can someone tell me what I did wrong or copy is buggy?

Thanks,
Jenny
