The advantages are self-evident to these programmers; and their lack comes as a shocking disappointment when they start to write application code for PostgreSQL*. The absence of packages and inner subprograms is huge. The absence of parameterizable anonymous blocks is a smaller limitation.

Not following. To be exposed they have to exist and that is not the case
in the community Postgres. The relevant question would seem to be, how
do I get these features built?
