pub const GEONAMES_SCHEMA_VERSION: i64 = 2;Expand description
Schema version stamp. Bump whenever the column layout changes so
geonames_schema_is_current can detect a stale on-disk DB and
trigger a rebuild.
v2: added feature_code (PPLC / PPLA / PPLA2 / PPL / …). Lets us
prefer real cities over GeoNames “PPL” entries that inherit
a metro-wide population — e.g. Rasapudipalem (PPL, pop
1,728,128 in upstream data) shouldn’t outrank Visakhapatnam
(PPLA2, pop 1,063,178).
