    Recommended action: Use the pgvector/pgvector:pg<major> image (same major as your data), install postgresql-<major>-pgvector on the server, or pick a hosted provider with pgvector; then CREATE EXTENSION vector in each database.
    
    Option: Install pgvector on the server [evidence: official_recommended_action]
    Applies when: See record scope.
    Steps:
    1. docker: image: pgvector/pgvector:pg17 (match your PG major)
    2. apt: sudo apt install postgresql-17-pgvector
    3. psql -c 'CREATE EXTENSION IF NOT EXISTS vector'
    Expected: Command proceeds without the error.
