Storing a backup of the database before upgrading

[Emilien Klein <emilien+debian@klein.st>]

I'm working on the upgrade steps needed for GNU Health 2.0.

Their README file lists making a copy of the database as the second step, which seems like a very good idea:

    pg_dump gnuhealth181 > backup181.sql

My question is where in the filesystem on Debian should I put these backup copies? Is there another package part of Debian Med that is making backups of it's data[base] before upgrading? How is that handled?

Or would backing up before upgrading be a feature already baked into dbconfig-common and I'm just not opening my eyes enough? ([0] mentions backing up, but I can't find any other mention elsewhere)
