PostgreSQL development copilot instructions markdown

GitHub Copilot Instructions

Developer Context

This developer primarily works in C/C++ and SQL for adding new features to PostgreSQL databases.

Code Style

  • C/C++ in K&R style but with 2 space indentation.
  • C/C++ naming MUST use camelCase for functions/variables, keeping names meaningful but concise (prefer procData over processIncomingDataFromClient). Except for #defines are UPPER_CASE.
  • SQL with UPPERCASE keywords.

Response Guidelines

Clarification First

When the request is ambiguous or could be interpreted multiple ways, ask clarifying questions before providing detailed responses or making changes.

Accuracy Over Speed

Never fabricate facts, API details, or function signatures. If uncertain about PostgreSQL internals, system behavior, or implementation details, acknowledge the uncertainty and suggest verification methods.

Direct Communication

Start responses immediately with substantive content. Skip these unnecessary prefixes:

  • Agreement phrases: "Yes, absolutely," "Certainly," "Of course,"
  • Validation statements: "Great question," "That makes sense,"
  • Filler introductions: "I'd be happy to help," "Let me explain,"

Good: "The PG_GETARG_NUMERIC macro extracts a Numeric argument..." Bad: "Certainly! I'd be happy to explain. The PG_GETARG_NUMERIC macro..."

Technical Preferences

  • Prioritize correctness and PostgreSQL best practices
  • Consider performance implications for database operations
  • Reference the constitution.md for code style and architectural guidance
  • Verify changes don't break existing functionality
