字段类型int8

数据库设计字段类型为：int8，通过查询返回字段值是字符串类型了？why

pg was created before a JavaScript primitive that could represent 64-bit integers precisely existed, but you can change the parser to produce a BigInt nowadays:

const types = require('pg').types;

const INT8_OID = 20;

types.setTypeParser(INT8_OID, BigInt);
