I've always been fine with the default, and in fact agree with it.  The
OpenACS project recommends a 16KB default for PG 7.0, but that's only so
we can hold reasonable-sized lzText strings in forum tables, etc.

I was only lamenting the fact that the world seems to have the impression
that it's not a default, but rather a hard-wired limit.
