The Great Britain data (.osm.pbf) downloaded from http://download.geofabrik.de/europe.html and loaded into PostGIS database. I figured out there are some missing data in the downloaded database compared to what you see on https://www.openstreetmap.org/.
A few examples are - 92344357 (Edited about 1 year ago), 151507677 (Edited 3 months ago).
Any possible reasons for this?
151507677 and 92344357 are ways, not nodes. Instead of osm_nodes you have to search for them in osm_ways.
See OSM elements for an explanation of the basic OSM elements, i.e. nodes, ways and relations.
