Thanks!
FreeBSD users already have the choice between zoneinfo from base or
the misc/zoneinfo port if for some reason they want to control tzdata
updates separately. PostgreSQL and FreeBSD both track tzdata closely,
and both pushed a commit for version 2019c into their stable branches
within a couple of weeks of it being released, so I don't foresee any
problem with this change, and staying in sync with libc seems to
outweigh any other concerns IMHO.
