What it does

Reviewing Oracle To Postgres Migration is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Identifies Oracle-to-PostgreSQL migration risks by cross-referencing code against known behavioral differences (empty strings, refcursors, type coercion, sorting/collations, UNION ALL planner risks, materialized-view refresh requirements, timestamps, concurrent transactions, etc.). Use when planning a database migration, reviewing migration artifacts, or validating that integration tests cover Oracle/PostgreSQL differences.

Its SKILL.md is about 800 tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files, including reference files (for example `references/REFERENCE.md`, `references/empty-strings-handling.md` and `references/no-data-found-exceptions.md`).

It sits in Databases, covering Database migrations and Integration testing. It works with PostgreSQL. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.

When your agent uses it

  • Planning a database migration
  • Reviewing migration artifacts
  • Validating that integration tests cover Oracle/PostgreSQL differences

Example prompts

  • “Use the reviewing-oracle-to-postgres-migration skill to identify Oracle-to-PostgreSQL migration risks by cross-referencing code against known…”
  • “/reviewing-oracle-to-postgres-migration”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit 727ff2e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Reviewing Oracle To Postgres Migration loads about 798 tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 117 tokens; SKILL.md has 295 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~798
With references · SKILL.md plus every file in references/, read only if the agent opens them
~16k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Identifies Oracle-to-PostgreSQL migration risks by cross-referencing code against known behavioral differences (empty strings, refcursors, type coercion, sorting/collations, UNION ALL planner risks, materialized-view refresh requirements, timestamps, concurrent transactions, etc.). Use when planning a database migration, reviewing migration artifacts, or validating that integration tests cover Oracle/PostgreSQL differences.

Oracle-to-PostgreSQL Database Migration

Surfaces migration risks and validates migration work against known Oracle/PostgreSQL behavioral differences documented in the references/ folder.

When to use

  1. Planning — Before starting migration work on a procedure, trigger, query, or refcursor client. Identify which reference insights apply so risks are addressed up front.
  2. Validating — After migration work is done, confirm every applicable insight was addressed and integration tests cover the new PostgreSQL semantics.

Workflow

Determine the task type:

Planning a migration? Follow the risk assessment workflow. Validating completed work? Follow the validation workflow.

Risk assessment workflow (planning)
Risk Assessment:
- [ ] Step 1: Identify the migration scope
- [ ] Step 2: Screen each insight for applicability
- [ ] Step 3: Document risks and recommended actions

Step 1: Identify the migration scope

List the affected database objects (procedures, triggers, queries, views) and the application code that calls them.

Step 2: Screen each insight for applicability

Review the reference index in references/REFERENCE.md. For each entry, determine whether the migration scope contains patterns affected by that insight. Read the full reference file only when the insight is potentially relevant.

Step 3: Document risks and recommended actions

For each applicable insight, note the specific risk and the recommended fix pattern from the reference file. Flag any insight that requires a design decision (e.g., whether to preserve Oracle empty-string-as-NULL semantics or adopt PostgreSQL behavior).

Validation workflow (post-migration)
Validation:
- [ ] Step 1: Map the migration artifact
- [ ] Step 2: Cross-check applicable insights
- [ ] Step 3: Verify integration test coverage
- [ ] Step 4: Gate the result

Step 1: Map the migration artifact

Identify the migrated object and summarize the change set.

Step 2: Cross-check applicable insights

For each reference in references/REFERENCE.md, confirm the behavior or test requirement is acknowledged and addressed in the migration work.

Step 3: Verify integration test coverage

Confirm tests exercise both the happy path and the failure scenarios highlighted in applicable insights (exceptions, sorting, UNION ALL behavior/performance risks, refcursor consumption, concurrent transactions, timestamps, materialized-view freshness, etc.).

Step 4: Gate the result

Return a checklist asserting each applicable insight was addressed, migration scripts run, and integration tests pass.
