pg_fetch_row — 提取一行作为枚举数组
$result
[, int $row
] )
pg_fetch_row() 根据指定的 result 资源提取一行数据（记录）作为数组返回。每个得到的列依次存放在数组中，从偏移量 0 开始。
Note: 此函数将 NULL 字段设置为 PHP
NULL值。
result
PostgreSQL query result resource, returned by pg_query(), pg_query_params() or pg_execute() (among others).
row
Row number in result to fetch. Rows are numbered from 0 upwards. If
omitted or NULL, the next row is fetched.
An array, indexed from 0 upwards, with each value
represented as a string. Database NULL
values are returned as NULL.
返回的数组和提取的行相一致。如果没有更多行 row 可提取，则返回 FALSE。
