Hmmm ... what I ended up committing was code that special-cased the
common cases where you only have one or the other, ie

/*
* We don't worry about singular versus plural here, since the English
* rules for that don't translate very well. But we can at least avoid
* the case of zero items.
*/
if (notherbackends > 0 && npreparedxacts > 0)
errdetail("There are %d other session(s) and %d prepared transaction(s) using the database.",
notherbackends, npreparedxacts);
else if (notherbackends > 0)
errdetail("There are %d other session(s) using the database.",
notherbackends);
else
errdetail("There are %d prepared transaction(s) using the database.",
npreparedxacts);

Your proposal seems fine for the first case but a bit stilted for the
other two. Or maybe that's just me.

Of course, we don't *have* to do it as above at all, if "0 prepared
transactions" doesn't bother people.

Ideas anybody?
