Well, I spent a little time googling on this, and dug through Oracle
documents that seem to have been written by marketroids who think
"componentize" is a verb :-( ... but by the time my brain went numb,
I hadn't actually seen anything that hasn't been in Postgres for years.

What you need to make clear to them is that their existing code base
isn't likely to be worth a dime --- if they don't mind recoding, the
functionality is probably all there, but there will not be any
compatibility of details. There are no standards covering this stuff.
