I see that we currently have five links to wiki.postgresql.org in
release notes and four more in the rest of the docs. Are people OK
with adding this link to the docs on max_connections? (Feel free to
improve it before answering if you have qualms about the specifics
on that page.)
We do seem to get an awful lot of posts (between here and
StackOverflow) from people who assume they need one database
connection per active user, and then are surprised that performance
is horrible.
If we get consensus on linking to this I'll put together a patch to
make a brief comment in the docs with a link to the Wiki.
