Migrate a Ruby on Rails application from Oracle Database to PostgreSQL — schema differences (NUMBER to BIGINT/DECIMAL, VARCHAR2 to VARCHAR, CLOB/BLOB to TEXT/BYTEA, sequences, ROWID, hierarchical queries, PL/SQL packages), Oracle Enhanced adapter to pg gem, data migration via ora2pg, the dual-write cutover. Use when leaving Oracle for Postgres, the user mentions ora2pg, Oracle Enhanced adapter, NUMBER columns, VARCHAR2, sequences, ROWNUM, CONNECT BY, or asks how to escape Oracle.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'db-migration-oracle-postgres' ] || [ -L ~/.agents/skills/'db-migration-oracle-postgres' ]; then echo 'A skill folder named db-migration-oracle-postgres already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/MadBomber/experiments' "$d" && git -C "$d" checkout --quiet '8139ff68e8895b544661aa2ba8b53268d68652bc' -- 'ai_misc/skills/rails-skills/23-db-migration-oracle-postgres' && mkdir -p ~/.agents/skills && cp -R "$d"/'ai_misc/skills/rails-skills/23-db-migration-oracle-postgres' ~/.agents/skills/'db-migration-oracle-postgres' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'db-migration-oracle-postgres' ~/.claude/skills/'db-migration-oracle-postgres' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
