OK, that makes it come a bit into focus. I think what pg_restore tried
to send was

COPY temp_measurement FROM STDIN;
7094982 ... rest of row 1 ...
67459 ... rest of row 2 ...

and the COPY command failed because of the stated reason, and then the
backend found itself chewing on a lot of data that was being sent as SQL
commands (because back then pg_restore depended on feedback from the
backend to tell whether an archive entry was COPY data or SQL commands).

So the bottom line here is you're trying to restore into a table that's
not there. How come? I suppose you were trying a data-only restore,
else this is a pg_dump or pg_restore bug.

Another point is that AFAICT 8.0 pg_restore does know enough to stop
if the COPY command fails --- least the case seems to work for me.
[ digs in CVS logs... ] Oh, it seems we fixed that in 8.0.7:

2006-02-05 15:59 tgl

* src/bin/pg_dump/: pg_backup_archiver.c, pg_backup_archiver.h,
pg_backup_db.c (REL8_0_STABLE): Fix pg_restore to properly discard
COPY data when trying to continue after an error in a COPY
statement. Formerly it thought the COPY data was SQL commands, and
got quite confused.

Stephen Frost

So I suppose you're running some earlier 8.0.x subrelease, in which case
an update would be an extremely good idea.
