Steps to reproduce
@Bean
public DataSource myDataSource(){
DataSource root = DataSourceBuilder.create()
.url("jdbc:postgresql://117.72.36.124:5432/spring-ai?currentSchema=public")
.username("postgres")
.password("postgres")
.build();
return root;
}

@Bean
public VectorStore vectorStore(@Qualifier ("myDataSource") DataSource myDataSource, ZhiPuAiEmbeddingModel embeddingModel) {
     JdbcTemplate jdbcTemplate = new JdbcTemplate(myDataSource);
    return PgVectorStore.builder(jdbcTemplate, embeddingModel)
            .dimensions(2048)                    // Optional: defaults to model dimensions or 1536
            .distanceType(COSINE_DISTANCE)       // Optional: defaults to COSINE_DISTANCE
            .indexType(HNSW)                     // Optional: defaults to HNSW
            .initializeSchema(true)              // Optional: defaults to false
            .schemaName("public")                // Optional: defaults to "public"
            .vectorTableName("vector_store")     // Optional: defaults to "vector_store"
            .maxDocumentBatchSize(10000)         // Optional: defaults to 10000
            .build();
}

spring.ai.vectorstore.type=false

Expected behavior

Wish to tell me how should I configure schema,or is this a misbehavior?

log.txt

Start with the PgVectorStore.builder configuration in the reproduction and inspect log.txt for the failing schema initialization statement. Determine whether schemaName("public") and initializeSchema(true) should prevent the PostgreSQL error; done means establishing whether this is a configuration issue or a PgVectorStore initialization bug.
