load part of the column from csv file to a table

[Mad-Apes]

Hello,
This version allow users load part of the column from csv file to a postgres table.
I add two parameter. One is CSV_FIELDS means columns in a csv file. The other parameter is FINAL_FIELDS, this means colomns in a postgres table.
for example：
CSV_FIELDS=table_name,params_name,description,params_value,default_value,range_operator

FINAL_FIELDS=table_name,params_name,PP,MM

If the column in FINAL_FIELDS does not in CSV_FIELDS, then load this column to table. for example, PP does not in CSV_FIELDS, then PP will load to table.

I provide a file bulkload_cfg_report.ctl. You can look over it.
