Allow `pg_dump` and `psql` symlinks to persist between upgrades
In https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/doc/settings/database.md#using-a-non-packaged-postgresql-database-management-server we document how to symlink the correct version of pg_dump
and psql
for users with an external database. However, this does not seem to survive upgrades. Can we create a method of handling this that will survive upgrades?
