You could provide a column list:
COPY tablename (col1name, col2name, ..., col17name) FROM ...
Or, easier than loading/dumping through another database, run the
file through a filter that adds the numbering:
perl -lne 'print "$_|$."' file.txt > file_numbered.txt
If the file were large and you didn't want to make a copy of it
then you could use a script like this:
#!/usr/bin/perl -ln
BEGIN {print "copy tablename from stdin delimiter '|';";}
print "$_|$.";
END {print "\\."} # should also work without this line
Run the script and pipe the output into psql:
script_name file.txt | psql database_name
