You can use qpkg to find those packages that depend upon another:

# qpkg -q sys-libs/db

Check out man qpkg for more info.

Really? Is there a tool to query the dependences of those?

Then what does the following mean? Is it unreliable?

sys-libs/db-1.85-r1
DEPENDED ON BY:
app-arch/rpm-4.2
dev-lang/perl-5.8.5-r5
dev-lang/python-2.3.4-r1
mail-mta/postfix-2.1.5-r2
sys-devel/libperl-5.8.5
sys-libs/pam-0.77-r6

and on and on for all the installed versions.

it mean that some packages have an explicit depend on it.
But this is _not_ required, and probably there are many more that depend
on db.

What are you asking? if it is "do all of the following depend on db, or
is this a mistake?" the answer is "yes they all depend on db"
