Not personally familiar with Singularity, but this post looks like it
should help:

   
https://www.linuxwave.info/2022/04/running-postgresql-database-using.html

The example command they have there is:

   singularity pull docker://postgres:14.2-alpine3.15

So the format of the url *seems* like it should be:

   docker://postgres:16.1

That just pure guess work though. :)
