That is all good, but how is that related to the issue at hand? We have
a problem as it is with development and testing resources for PostgreSQL,
so your solution is to make everyone use PostgreSQL instead of MySQL
to solve that problem?

How is this going to help with the main issue (lack of human resources
on the PostgreSQL side)?

People who develop and deploy Drupal use mainly MySQL.

Should we give them more work to solve the problem of lack or
resource (or the pgSQL folk not contributing)?

pgSQL is a better database than MySQL (at least MyISAM). No one is
saying otherwise. The issue is how the community is made up, not a technical

one.
