Refactor Linked Server Logic: Eliminate `OPENQUERY` and four-part naming conventions, replacing them with direct, high-performance PostgreSQL

queries.

Temp Table Optimization: Refactor extensive temporary table usage

(`#Temp`) to PostgreSQL-specific implementations (Temporary Tables,

CTEs, or Arrays) to optimize memory usage and execution speed.

AI-Assisted Development: Utilize Large Language Models (LLMs) and automated SQL translation tools (e.g., ChatGPT, Claude, Ispirer, AWS SCT) to

generate initial code drafts, then manually refine and validate the output.

Validation: Execute rigorous testing to ensure the converted procedures
