dbf2pg - Insert xBase-style .dbf-files into a PostgreSQL-table

There is an option "-s oldname=newname", which changes the old field name of
  the dbf-file to the newname in PostgeSQL. If the length of the new name is 0,
  the field is skiped. If you want to skip the first field of the dbf-file,
  you get the wildest error-messages from the backend.
  dbf2pg load the dbf-file via "COPY tablename FROM STDIN". If you skip the
  first field, it is an \t to much in STDIN.

A fix could be an counter j=0, which increments only, if a field is imported
(IF (strlen(fields[h].db_name)> 0) j++. And only if j > 1 (if an other field is
imported) the \t is printed.

An other small bug in the README:
-s start
              Specify  the  first record-number in the xBase-file
              we will insert.
should be
-e start
              Specify  the  first record-number in the xBase-file
              we will insert.

+       -s oldname=[newname][,oldname=[newname]]
 	      Change the name of a field from oldname to newname.
 	      This  is	mainly	used to avoid using reserved SQL-
-	      keywords. Example:
-	      -s SELECT=SEL,COMMIT=doit
+	      keywords.  When the new fieldname is empty, the field
+	      is skipped in both the CREATE-clause and the
+	      INSERT-clauses, in common words: it will not be present
+	      in the SQL-table.
+		  Example:
+	      -s SELECT=SEL,remark=,COMMIT=doit
 	      This is done  before  the  -f  operator  has  taken
 	      effect!
