set to the smaller value of either 0.75* total RAM amount, or the sum of buff/cache, free RAM, and shared buffers in the output of free command, and is used to give PostgreSQL a hint about how much total cache space is available. This refers to caches in main memory, not CPU ca...
SELECTCREATE_EXTENSION('vector'); 备注 若要禁用扩展,请使用drop_extension() 概念 向量相似性 向量相似性是一种通过将两个项目表示为向量(即一系列数字)来衡量其之间相似程度的方法。 向量通常用于表示数据点,其中向量的每个元素表示数据点的某个特征或属性。
