Обсуждение: [GENERAL] tzdata version

As i understand it, the tzdata on which the timezone information is based is updated regularly (semi-manually) in https://github.com/postgres/postgres/tree/master/src/timezone

Am i correct in stating that there is currently no way to update the tzdata database except by recompiling postgres after a new version of the tz database has been adapted for postgres ?

Is there a way to introspect the current version of the tzdata release (2014j, 2016h, 2017b, ..) that is embedded in a pre-compiled postgres (at runtime or in another way) ?

Thanks

Jérôme
