根据文档说明,如果使用character varying而没有指定长度,该类型接受任何大小的字符串,后者是PostgreSQL的扩展。此外,PostgreSQL还提供了text类型,它存储任意长度的字符串。虽然text类型不属于SQL标准,但其他几个SQL数据库管理系统也具有该类型。那么这两种数据类型有什么区别呢? - Adam Matan...

SQL定义了两种基本的字符类型:character varying(n)和character(n),这里的n是一个正整数。两种类型都可以存储最多n个字符的字符串。 试图存储更长的字符串到这些类型的字段里会产生一个错误, 除非超出长度的字符都是空白,这种情况下该字符串将被截断为最大长度。
