[CentOS] Yum-complete-transaction wants to wipe my system out

After some enabling/disabling new repos (pgdg for PostgreSQL
specifically) and admittedly some yum action that may have gone
uncompleted, I am advised to run yum-complete-transaction. However,
when I attempt to do this, yum warns that 225 packages will be erased,
all of which I deeply care for. How can I safely back out of this
situation?
Thank you in advance
