Spring AI PGVector schema initialization doesn't work when datasource auto-commit is disabled.

Bug description If auto commit is disabled, jdbcTemplate.execute doesn't get committed and is rolled back: https://github.com/spring-projects/spring-ai/blob/690d242c22a70d5d3ebe40436fdbca8a1e481e44/vector-stores/spring-ai-pgvector-store/src/main/java/org/springframework/ai/vectorstore/pgvector/PgVectorStore.java#L421

Environment Spring AI v1.0.0-M6 Spring Boot 3.4.3 Java 17 PGVector store Hikari datasource with auto-commit disabled

Steps to reproduce Start an application with above configuration.

Expected behavior Schema should be correctly initialized.

Minimal Complete Reproducible example

Workaround

Commit manually:

    jdbcTemplate.execute(
            new ConnectionCallback<String>() {
                public String doInConnection(Connection con) throws SQLException {
                    con.createStatement().execute("CREATE EXTENSION IF NOT EXISTS vector");
                    con.createStatement().execute("CREATE EXTENSION IF NOT EXISTS hstore");
                    con.createStatement().execute("CREATE EXTENSION IF NOT EXISTS \"uuid-ossp\"");
                    con
                        .createStatement()
                        .execute(
                            String.format(
                                """
