Re: pg_system_identifier()

All,

I think we've gotten a bit off the track of the proposed patch, which is
designed to report the system_identifier string currently in
pg_controldata, nothing more.

I'm going to reverse my vote, and vote against this patch.  The reason
why is that I think we should instead have a function:

pg_controldata(parameter text)

... which would report *all* strings in pg_controldata.  Hence, you'd do
instead:

pg_controldata('system identifier')

This will hopefully spare us from 15 patches incrementally adding all of
the individual items in controldata.
