I am using vector tiles from PostGIS, Geoserver for the world layer, I have multiple layers for the global level, I have seen multiple holes and missing tiles of some boundaries in the layer of vector tiles.

I have tried multiple methods to resolve the issue still not found the solution.

  1. geometry st_isvalid,
  2. geometry topology.

WMS layer with the same geometry. no hollow.

enter image description here

same layer for vector tiles hole in Layer

Is this related to the multiPolygons/geometryCollection issue or something else?

    you say "I have tried multiple methods to resolve the issue still not found the solution." - what are they? Also what are you using to render the vector tiles?

Geometry must be valid use st_simplifypreservetopology and ensure that you have all valid geometries (>=4 vertices).
