Why is this?  (This isn't a criticism, just a question.)

In the somewhat-early days of PostgreSQL development, there was an
idea that nifty new features could be added without logging (it's more
complicated than this, but bear with me) support.  But the effect was
that some of those features remained forever 2d class citizens.  Is
that what's happening here?  Because if so, it'd be really great to
know that now so that I can decide either (1) to fund development of
those features or (2) to find something that will promise not to lose
my data across system crashes.  (I will state now that (1) is
unlikely, given what I'm looking at in terms of profit; but I might be
willing to trade, and some money could be involved.)

>From the documentation state, it's pretty clear that the business
features aren't really the priority.  But losing posted invoices moves
from "not a priority" to "this is a toy".  I had no idea that business
actions weren't logged, and that isn't a prominently-displayed note in
the manual last I checked, either.

Best,
