Suggestion:
Use INFORMATION_SCHEMA for everything that INFORMATION_SCHEMA covers.
That way, there will not be needless duplications.
Create new tables with foreign keys to the INFORMATION_SCHEMA for
everything else.
Alternative suggestion:
Create any sort of magic, pg-specific schema you want, and create views
that map the stuff back to the INFORMATION_SCHEMA to fill
INFORMATION_SCHEMA out completely.
Both methods are equally good to me.
What would be painful (in my view) is if the new "custom" schema has
INFORMATION_SCHEMA data in it, and the INFORMATION_SCHEMA does not
contain that needed information (IOW: INFORMATION_SCHEMA lags behind
because the PG specific schema gets lots of work and the
INFORMATION_SCHEMA gets secondary attention).
As long as I get my INFORMATION_SCHEMA views, and as long as they are
fully populated, I would not care at all if there were additional
information somewhere else.
