Given a table of candidates and their technical skills, list the candidate IDs of candidates who have more than 2 technical skills. 

**Assumption:**
- There are no duplicates in the `candidates` table.

### `candidates` Table:
|**Column Name**|**Type**|
|:----|:----|
|candidate_id|integer|
|skill|varchar|

### `candidates` Example Input:
|**candidate_id**|**skill**|
|:----|:----|
|123 | Python|
|123 | Tableau|
|123 | PostgreSQL|
|234 | PowerBI|
|234 | SQL Server|
|345 | Python|
|345 | Tableau|

### Example Output:
|**candidate_id**|
|:----|
|123|

Candidate 123 is the only ID that is outputted because they have more than two technical skills (Python, Tableau, and PostgreSQL).
