In my case, no. I try to get through the general mail, but if I'm
short on time, it would be really nice to be able to ignore the day's
postings to general, but still know that I can find some things of
particular interest to me (i.e., stuff I really don't want to miss) on
the performance list.

No. It's a matter not of what else in general would apply, but how
does one get at least the most important stuff when one is short
of time.

That doesn't really matter, I think. People interested in both
topics can easily subscribe to both lists. The real question, to
my mind, is "are there people who would find it useful to see just
performance-related stuff." Which I think is true.
Thus, I'd like to see a separate performance list.
Here's my stab at a charter:
The pgsql-performance list is for technical discussion relating
to the performance (speed and efficiency) of PostgreSQL. In
particular, discussions of the performance of common or uncommon
operations on very large databases are welcome.
However, "why isn't this query using this index?" questions
are strongly discouraged, unless you understand the PostgreSQL
optimizer, are proposing changes to it, and have data to show
that the change improves the optimizer in a wide variety of
situations, not just your particular one.
This description could probably be made a lot better, but I think
you get the idea. The reasons for the second paragraph should be
fairly obvious to hacker types, if not less technical users of
PostgreSQL.
