Is \\n\\n or \\r\\r\\n best to use between paragraphs of text in a database?

The mySQL client I use on my Mac, Querious, adds

between paragraphs while editing the contents of a column. However, the textarea HTML tag on my website inserts \r\r
between paragraphs. Which one,

or \r\r
is more of an accepted standard for storing multiple paragraphs in a database?

from a database perspective, whichever one you want is fine

this is not really a database question
