Just remember that trust is just that, trust. If someone knows a valid
username they have access, subject to other conditions set in pg_hba.conf.

It does if you want to backup the state of the entire cluster. Could be
that DaVinci is including things in the template1 and postgres databases
that are needed. The other thing that pg_dumpall gets you is data global
to the cluster:

https://www.postgresql.org/docs/9.5/static/app-pg-dumpall.html

" ... pg_dumpall also dumps global objects that are common to all
databases. (pg_dump does not save these objects.) ..."

Though you can have your cake and eat it to by using pg_dump for
individual databases and then

pg_dumpall -g

where -g is:

"-g
--globals-only

Dump only global objects (roles and tablespaces), no databases.
