加载/访问数据库:

sudo -u postgres psql     ## or: sudo su postgres

postgres=# \i northwind.postgre.sql;

postgres=# \d
                List of relations

             Table "public.customers"
    Column    |         Type          | Modifiers

ERROR:  column "city" does not exist
LINE 1: SELECT DISTINCT City FROM customers ORDER BY City;
                        ^

# ... use use double-quotes if your column name
# (etc.) contains some uppercase characters:

postgres=# SELECT DISTINCT "City" FROM customers ORDER BY "City";
      City
