I have the following note in my (much too long) to-do list:

: psql.c doesn't appear to cope correctly with quoted newlines in COPY data;
: if one falls just after a buffer boundary, trouble!
: Does fe-exec.c work either??

(This note is some months old, and may or may not still apply since
Peter's rework of psql.)  It could be that your dataset is hitting this
problem or a similar one.  A buffer-boundary problem would explain why
the error seems to be so dataset-specific.

It sure sounds like psql is failing to recognize the trailing \.
of the COPY data.
