Describe the issue
After fixing the pagination issue in Postgres table results (PR #98), similar code patterns exist in ClickHouse that should be consolidated to reduce code duplication.

Expected behavior
The pagination logic should be consolidated into a shared utility that both Postgres and ClickHouse implementations can use, reducing code duplication and simplifying maintenance.

Additional context
Create shared pagination utilities for reuse across database types
Update both Postgres and ClickHouse implementations to use the common code
Eliminate duplicate logic and improve code maintainability
Ensure consistent pagination behavior across different database implementations
