- Martin: pool_size=8 (prevents overwhelming PostgreSQL with concurrent queries) - Martin: gis_terenuri minzoom 10→14, gis_cladiri minzoom 12→15 (PMTiles serves z0-z14, no point in Martin generating those) - PostGIS: add compound index layerId+geom for Martin view queries - PostGIS: add B-tree index on layerId for LIKE filtering in views Fixes 90% CPU on PostgreSQL during cold tile loads at detail zoom levels.
