Overwritten rpm versions for proj72-* - Mailing list pgsql-pkg-yum

It has recently come to my attention that versioned RPMs for the following artifacts were overwritten in the PostgreSQL common yum repo  at: https://download.postgresql.org/pub/repos/yum/common/redhat/rhel-7Server-x86_64/

I've observed this for at least the following 2 RPMs: 

proj72-7.2.1-1.rhel7.x86_64.rpm 

For example, for proj72-devel-7.2.1-1.rhel7.x86_64.rpm, the data for the previous artifact was:

Currently, the package that resides at that path has:

Reaching out here to find out if the overwriting of versioned RPMs was expected, since it seems highly irregular. 

Thanks in advance,
