I'm afraid that we will get pushback from vendors who say that removing an
exported function is an ABI break. At minimum, certain people will insist
that this requires an increment in the shlib major version for libpq.so.
And that will cause a lot of pain, because it'd mean that v13 libpq.so
is no longer usable by applications built against older releases.
On the whole, I think benign neglect is the best policy here.
