[Impact]

 * MRE for latest stable fixes of Postgres released on May 2021

[Test Case]

 * The Postgres MREs traditionally rely on the large set of autopkgtests
   to run for verification. In a PPA those are all already pre-checked to
   be good for this upload.

[Regression Potential]

 * Upstreams tests are usually great and in additon in the Archive there
   are plenty of autopkgtests that in the past catched issues before being
   released.
   But never the less there always is a risk for something to break. Since
   these are general stable releases I can't pinpoint them to a most-likely
   area.
   - usually this works smoothly except a few test hickups (flaky) that need to be
     clarified to be sure. Pre-checks will catch those to be discussed upfront (as last time)

[Other Info]

 * This is a reoccurring MRE, see below and all the references
 * AFAICS no CVEs this time
