feat(writer): 🎉 Enhance primary key handling and add tests

* Implement checks for existing primary keys before adding new ones.
* Drop auto-generated primary keys if they exist.
* Add tests for primary key existence and column size specifiers.
* Improve type conversion handling for PostgreSQL compatibility.

+| Object Type       | Prefix      | Format                             | Example                  |
+| ----------------- | ----------- | ---------------------------------- | ------------------------ |
+| Primary Key       | `pk_`       | `pk_<schema>_<table>`              | `pk_public_users`        |
+| Foreign Key       | `fk_`       | `fk_<table>_<referenced_table>`    | `fk_posts_users`         |
+| Unique Constraint | `uk_`       | `uk_<table>_<column>`              | `uk_users_email`         |
+| Unique Index      | `uidx_`     | `uidx_<table>_<column>`            | `uidx_users_email`       |
+| Regular Index     | `idx_`      | `idx_<table>_<column>`             | `idx_posts_user_id`      |
+| Check Constraint  | `chk_`      | `chk_<table>_<constraint_purpose>` | `chk_users_age_positive` |
+| Sequence          | `identity_` | `identity_<table>_<column>`        | `identity_users_id`      |
+| Trigger           | `t_`        | `t_<purpose>_<table>`              | `t_audit_users`          |
+| Trigger Function  | `tf_`       | `tf_<purpose>_<table>`             | `tf_audit_users`         |
+
+## Naming Rules by Object Type
+
+### Primary Keys
+
+**Pattern:** `pk_<schema>_<table>`
+
+- Include schema name to avoid collisions across schemas
+- Use lowercase, snake_case format
+- Examples:
+  - `pk_public_users`
+  - `pk_audit_audit_log`
+  - `pk_staging_temp_data`
+
+### Foreign Keys
+
+**Pattern:** `fk_<table>_<referenced_table>`
+
+- Reference the table containing the FK followed by the referenced table
+- Use lowercase, snake_case format
+- Do NOT include column names in standard FK constraints
+- Examples:
+  - `fk_posts_users` (posts.user_id → users.id)
+  - `fk_comments_posts` (comments.post_id → posts.id)
+  - `fk_order_items_orders` (order_items.order_id → orders.id)
+
+### Unique Constraints
+
+**Pattern:** `uk_<table>_<column>`
+
+- Use `uk_` prefix strictly for database constraints (CONSTRAINT type)
+- Include column name for clarity
+- Examples:
+  - `uk_users_email`
+  - `uk_users_username`
+  - `uk_products_sku`
+
+### Unique Indexes
+
+**Pattern:** `uidx_<table>_<column>`
+
+- Use `uidx_` prefix strictly for index type objects
+- Distinguished from constraints for clarity and implementation flexibility
+- Examples:
+  - `uidx_users_email`
+  - `uidx_sessions_token`
+  - `uidx_api_keys_key`
+
+### Regular Indexes
+
+**Pattern:** `idx_<table>_<column>`
+
+- Standard indexes for query optimization
+- Single column: `idx_<table>_<column>`
+- Examples:
+  - `idx_posts_user_id`
+  - `idx_orders_created_at`
+  - `idx_users_status`
+
+### Check Constraints
+
+**Pattern:** `chk_<table>_<constraint_purpose>`
+
+- Describe the constraint validation purpose
+- Use lowercase, snake_case for the purpose
+- Examples:
+  - `chk_users_age_positive` (CHECK (age > 0))
+  - `chk_orders_quantity_positive` (CHECK (quantity > 0))
+  - `chk_products_price_valid` (CHECK (price >= 0))
+  - `chk_users_status_enum` (CHECK (status IN ('active', 'inactive')))
+
+### Sequences
+
+**Pattern:** `identity_<table>_<column>`
+
+- Used for SERIAL/IDENTITY columns
+- Explicitly named for clarity and management
+- Examples:
+  - `identity_users_id`
+  - `identity_posts_id`
+  - `identity_transactions_id`
+
+### Triggers
+
+**Pattern:** `t_<purpose>_<table>`
+
+- Include purpose before table name
+- Lowercase, snake_case format
+- Examples:
+  - `t_audit_users` (audit trigger on users table)
+  - `t_update_timestamp_posts` (timestamp update trigger on posts)
+  - `t_validate_orders` (validation trigger on orders)
+
+### Trigger Functions
+
+**Pattern:** `tf_<purpose>_<table>`
+
+- Pair with trigger naming convention
+- Use `tf_` prefix to distinguish from triggers themselves
+- Examples:
+  - `tf_audit_users` (function for t_audit_users)
+  - `tf_update_timestamp_posts` (function for t_update_timestamp_posts)
+  - `tf_validate_orders` (function for t_validate_orders)
+
+## Multi-Column Objects
+
+### Composite Primary Keys
+
+**Pattern:** `pk_<schema>_<table>`
+
+- Same as single-column PKs
+- Example: `pk_public_order_items` (composite key on order_id + item_id)
+
+### Composite Unique Constraints
+
+**Pattern:** `uk_<table>_<column1>_<column2>_[...]`
+
+- Append all column names in order
+- Examples:
+  - `uk_users_email_domain` (UNIQUE(email, domain))
+  - `uk_inventory_warehouse_sku` (UNIQUE(warehouse_id, sku))
+
+### Composite Unique Indexes
+
+**Pattern:** `uidx_<table>_<column1>_<column2>_[...]`
+
+- Append all column names in order
+- Examples:
+  - `uidx_users_first_name_last_name` (UNIQUE INDEX on first_name, last_name)
+  - `uidx_sessions_user_id_device_id` (UNIQUE INDEX on user_id, device_id)
+
+### Composite Regular Indexes
+
+**Pattern:** `idx_<table>_<column1>_<column2>_[...]`
+
+- Append all column names in order
+- List columns in typical query filter order
+- Examples:
+  - `idx_orders_user_id_created_at` (filter by user, then sort by created_at)
+  - `idx_logs_level_timestamp` (filter by level, then by timestamp)
+
+## Special Cases & Conventions
+
+### Audit Trail Tables
+
+- Audit table naming: `<original_table>_audit` or `audit_<original_table>`
+- Audit indexes follow standard pattern: `idx_<audit_table>_<column>`
+- Examples:
+  - Users table audit: `users_audit` with `idx_users_audit_tablename`, `idx_users_audit_changedate`
+  - Posts table audit: `posts_audit` with `idx_posts_audit_tablename`, `idx_posts_audit_changedate`
+
+### Temporal/Versioning Tables
+
+- Use suffix `_history` or `_versions` if needed
+- Apply standard naming rules with the full table name
+- Examples:
+  - `idx_users_history_user_id`
+  - `uk_posts_versions_version_number`
+
+### Schema-Specific Objects
+
+- Always qualify with schema when needed: `pk_<schema>_<table>`
+- Multiple schemas allowed: `pk_public_users`, `pk_staging_users`
+
+### Reserved Words & Special Names
+
+- Avoid PostgreSQL reserved keywords in object names
+- If column/table names conflict, use quoted identifiers in DDL
+- Naming convention rules still apply to the logical name
+
+### Generated/Anonymous Indexes
+
+- If an index lacks explicit naming, default to: `idx_<schema>_<table>`
+- Should be replaced with explicit names following standards
+- Examples (to be renamed):
+  - `idx_public_users` → should be `idx_users_<column>`
+
+## Implementation Notes
+
+### Code Generation
+
+- Names are always lowercase in generated SQL
+- Underscore separators are required
+
+### Migration Safety
+
+- Do NOT rename objects after creation without explicit migration
+- Names should be consistent across all schema versions
+- Test generated DDL against PostgreSQL before deployment
+
+### Testing
+
+- Ensure consistency across all table and constraint generation
+- Test with reserved words to verify escaping

+- **Ordered Execution**: Scripts execute in Priority→Sequence→Name order

 - **Stop on Error**: Execution halts immediately on first error (default behavior)
 - **Progress Reporting**: Prints execution status to stdout
@@ -103,19 +103,40 @@ Scripts are sorted and executed based on:
 
 1. **Priority** (ascending): Lower priority values execute first
 2. **Sequence** (ascending): Within same priority, lower sequence values execute first
+3. **Name** (ascending): Within same priority and sequence, alphabetical order by name
 
 ### Example Execution Order
 
 Given these scripts:
 ```
-Script A: Priority=2, Sequence=1
+Script A: Priority=2, Sequence=1, Name="zebra"
-Script B: Priority=1, Sequence=3
+Script B: Priority=1, Sequence=3, Name="script"
