Impartial on NOTICE vs. WARNING, it could go either way for me.

I have to disagree strongly with this.  We have multiple PG instances
and often have cause to copy between them using data-only pg_dump.  On
the other side, I've never used pg_dump (data-only or not) to generate
something to load data into a different database.
