Bug: Vector index transaction issue

[mewim]

Kuzu version

v0.9.0

What operating system are you using?

macOS

Are there known steps to reproduce?

1. In kuzu shell, load data and create vector index

INSTALL vector;
LOAD vector;
CREATE NODE TABLE tbl (id int64 PRIMARY KEY, vec FLOAT[784]);
COPY tbl from "dataset/mnist/data.parquet";
CALL CREATE_VECTOR_INDEX(
                'tbl',
                'vec_index',
                'vec', metric := "l2");

2. After all the above cypher statements are done, in idle state, kill shell:

killall kuzu

3. It is expected to have the index in the database files but actuallly it is empty:

CALL SHOW_INDEXES() RETURN *;
