35394	Warning if 'postgres' database has been rename (e.g. DigitalOcean managed)	Jeffry Babb	nobody	"This warning is thrown if the 'postgres' database does not exist on the server.  DigitalOcean renames this database to 'defaultdb' which seems to raise this error in dango/db/backends/base/base.py

I have searched in the LIBPQ parameters can can't find a setting that allows me to specify this name change as Django seems to have hard-coded the search for the 'postgres' db name or is looking for it in a key called 'service' around line 193 and 218 in base.py.
