That is the expected behavior because PGvector doesn't support higher dimensions than 2000 when the HNSW indexing strategy is used. There is an ongoing discussion in the PGvector project to raise the limit to at least 4096: pgvector/pgvector#461.
This limitation is mentioned in the Spring AI documentation: https://docs.spring.io/spring-ai/reference/api/vectordbs/pgvector.html#_prerequisites.
