**Describe the unexpected behaviour**
Clickhouse parses enum object unexpectedly when enum object literal value is 08 or 09. I tried to debug the problem and it seems that  Which::type is returning Float64 and hence ENUMparser is throwing error.

**Notice  dot symbol after 8 literal value in generated SQL .  This is not happening for values 07,01,03... so on . This is failing for only ( = 08 and =09)**

**How to reproduce**
````
 :) CREATE TABLE t1 (`Road_Surface_Condition` Enum8('00 - Unkown' = 0,'07 - Others' = 07,'08 - Loose sand and gravel' = 8, '09 - Spilled liquid' = 9),objectId UInt32)Engine=MergeTree ORDER BY objectId

CREATE TABLE t1
(
    `Road_Surface_Condition` Enum8('00 - Unkown' = 0, '07 - Others' = 7, '08 - Loose sand and gravel' = 8, '09 - Spilled liquid' = 9),
    `objectId` UInt32
)
ENGINE = MergeTree
ORDER BY objectId

Query id: fc946666-baeb-49af-bda2-72df3fd5d6ea

Ok.

* Which ClickHouse server version to use
 v22.6

* Which interface to use, if matters
command line client. 

**Expected behavior**
Table should be created successfully with specified Enum column .

**Error message and/or stacktrace**
```
Received exception from server (version 22.3.6):
Code: 223. DB::exception: Received from localhost:9000. DB::exception: Elements of Enum data type must be of form: 'name' = number, where name is string literal and number is an integer. (UNEXPECTED_AST_STRUCTURE)
