You're right, the code at fault is here:

https://github.com/simonw/sqlite-utils/blob/1b09538bc6c1fda773590f3e600993ef06591041/sqlite_utils/db.py#L2213-L2231","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1243151184,
https://github.com/simonw/sqlite-utils/issues/434#issuecomment-1155794149,https://api.github.com/repos/simonw/sqlite-utils/issues/434,1155794149,IC_kwDOCGYnMM5E5ATl,9599,2022-06-14T23:09:54Z,2022-06-14T23:09:54Z,OWNER,"A test that demonstrates the problem:
```python
@pytest.mark.parametrize(""reverse_order"", (True, False))
def test_detect_fts_similar_tables(fresh_db, reverse_order):
    # https://github.com/simonw/sqlite-utils/issues/434
    table1, table2 = (""demo"", ""demo2"")
    if reverse_order:
        table1, table2 = table2, table1

    fresh_db[table1].insert({""title"": ""Hello""}).enable_fts(
        [""title""], fts_version=""FTS4""
    )
    fresh_db[table2].insert({""title"": ""Hello""}).enable_fts(
        [""title""], fts_version=""FTS4""
    )
    assert fresh_db[table1].detect_fts() == ""{}_fts"".format(table1)
    assert fresh_db[table2].detect_fts() == ""{}_fts"".format(table2)
```
The order matters - so this test currently passes in one direction and fails in the other:
```
>       assert fresh_db[table2].detect_fts() == ""{}_fts"".format(table2)
E       AssertionError: assert 'demo2_fts' == 'demo_fts'
E         - demo_fts
E         + demo2_fts
E         ?     +

```sql
CREATE VIRTUAL TABLE ""searchable_fts""
    USING FTS4 (text1, text2, [name with . and spaces], content=""searchable"")
```
OR like this:
```sql
CREATE VIRTUAL TABLE ""searchable_fts""
    USING FTS4 (text1, text2, [name with . and spaces], content=[searchable])
```
This fix looks to be correct to me (copying from the updated `test_with_trace()` test):

```python
            (
                ""SELECT name FROM sqlite_master\n""
                ""    WHERE rootpage = 0\n""

                ""        OR sql LIKE :like2\n""
                ""        OR (\n""
                ""            tbl_name = :table\n""
                ""            AND sql LIKE '%VIRTUAL TABLE%USING FTS%'\n""
