Hmm, is your build configured with --with-system-tzdata
(pg_config --configure would tell you)? If so, is that pointing at
a reasonable-looking tree of TZ data? It seems you don't have the
TZ data correctly installed in the 10.3 installation, but it's hard
to tell who to blame from this much info.
Typically the top of the TZ file tree should look like
$ ls /usr/share/zoneinfo
Africa/ Canada/ GB Indian/ Mexico/ ROK iso3166.tab
America/ Chile/ GB-Eire Iran NZ Singapore leapseconds
Antarctica/ Cuba GMT Israel NZ-CHAT Turkey posix/
Arctic/ EET GMT+0 Jamaica Navajo UCT posixrules
Asia/ EST GMT-0 Japan PRC US/ right/
Atlantic/ EST5EDT GMT0 Kwajalein PST8PDT UTC tzdata.zi
Australia/ Egypt Greenwich Libya Pacific/ Universal zone.tab
Brazil/ Eire HST MET Poland W-SU zone1970.tab
CET Etc/ Hongkong MST Portugal WET
CST6CDT Europe/ Iceland MST7MDT ROC Zulu
If you're not trying to rely on a platform-provided installation
of tzdata, then this ought to be under the share/ subdirectory
of the PG installation.
