根据2024 sql 生成2024 postgres sql

[sdhou]

修改了适合 postgres 的建表语句

DROP TABLE IF EXISTS area_code_2024;
CREATE TABLE area_code_2024 (
code BIGINT NOT NULL,
name VARCHAR(128) NOT NULL DEFAULT '',
level SMALLINT NOT NULL CHECK (level BETWEEN 1 AND 5),
pcode BIGINT,
category INTEGER,
PRIMARY KEY (code)
) WITH (fillfactor = 90);

-- 创建索引
CREATE INDEX area_code_2024_name_idx ON area_code_2024 (name);
CREATE INDEX area_code_2024_level_idx ON area_code_2024 (level);
CREATE INDEX area_code_2024_pcode_idx ON area_code_2024 (pcode);

-- 添加列注释
COMMENT ON COLUMN area_code_2024.code IS '区划代码';
COMMENT ON COLUMN area_code_2024.name IS '名称';
COMMENT ON COLUMN area_code_2024.level IS '级别1-5,省市县镇村';
COMMENT ON COLUMN area_code_2024.pcode IS '父级区划代码';
COMMENT ON COLUMN area_code_2024.category IS '城乡分类';
