Summary of Changes

Hello @dveeden, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the documentation for SQL CREATE USER and ALTER USER statements. It addresses an issue where certain grammar definitions were duplicated across these files, leading to redundancy. By removing these duplicate entries, the PR enhances the clarity and maintainability of the SQL statement reference documentation.

Highlights

• Grammar Definition Cleanup: Removed redundant RequireClauseOpt and RequireList grammar definitions from the CREATE USER and ALTER USER SQL statement documentation files. These definitions were duplicated and are now consolidated or removed to improve documentation consistency.

Code Review

This pull request correctly removes duplicate EBNF definitions for RequireClauseOpt and RequireList from the documentation for CREATE USER and ALTER USER. This change improves the clarity and accuracy of the syntax diagrams by removing redundant and outdated information. The changes are well-aligned with the goal of the pull request and improve the overall quality of the documentation. I have no further suggestions.
