psql has *no* business changing what it displays: if what came from the
server has a trailing newline, that had better be made visible.  Even if
we thought it was a good idea, it's about 25 years too late to reconsider
that.  However, xmlserialize()'s new indenting behavior isn't set in
stone yet, so we could contemplate chomping newlines within that.

The trailing newline is made visible by the little bent arrow character that appears at the right hand side. So you could still tell whether the value ended with a trailing newline. I agree that simply dropping the trailing newline before displaying the value would be a very bad idea.

What is benefit or usage of this trailing newline?

Personally, when I do some formatting I prefer adding newlines on client side before necessity of removing.
