Hmm, the code is quite clear about it:
/*
* We allow numeric timezone offsets up to 15:59:59 either way from Greenwich.
* Currently, the record holders for wackiest offsets in actual use are zones
* Asia/Manila, at -15:56:00 until 1844, and America/Metlakatla, at +15:13:42
* until 1867. If we were to reject such values we would fail to dump and
* restore old timestamptz values with these zone settings.
*/
#define MAX_TZDISP_HOUR 15 /* maximum allowed hour part */
Apparently this documentation reference got overlooked the last time
we changed that :-(. Will fix, thanks for the report!
