📝 WalkthroughWalkthroughThe documentation establishes PostgreSQL as the default relational provider, Neon as the PoC host, and Azure Flexible Server for shared deployments. It updates secrets, setup, migration, portability, testing, and SQLite preview guidance. ChangesPostgreSQL documentation alignment
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to This documentation change establishes PostgreSQL deployment guidance, but Azure pooled-connection instructions can bypass PgBouncer if the port is omitted, and database examples should make transport security explicit. Correcting these details will reduce deployment and data-transfer misconfiguration risk. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)
Full details: Description checkExplanation The description includes the closing issue, summary, documentation-only preview exemption, test plan, feedback focus, and related issue context. It omits detailed automated-check results and expanded setup steps, but it is mostly complete for a documentation-only change. Full details: Linked Issues checkExplanation The changes satisfy issue Full details: Out of Scope Changes checkExplanation The changes are limited to documentation, templates, examples, and an architecture decision record that support the linked issue. No unrelated functional code, Azure SQL data migration, or OpenFGA SQLite migration work is included. Full details: Docstring CoverageExplanation No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.

**issue (broader_impact):** The documentation declares Neon or Azure Flexible Server as the database host, but `infra/main.bicep`, `infra/README.md`, and `infra/migrate-db.ps1` still provision and target Azure SQL. Following the updated setup and deployment guidance therefore creates or migrates the old SQL Server database instead of the documented PostgreSQL database.
**Triggers:** When a developer provisions or migrates the environment using the repository's existing infrastructure scripts.
**Suggested fix:** Update the infrastructure and migration runbooks in the same cutover, or explicitly defer the new host documentation until the infrastructure change in #298 is merged.
```suggestion
| Neon PostgreSQL | **Documentation deferred until the infrastructure change in #298 is merged** | Key Vault `database-url` (+ `database-url-unpooled`) | Neon |
```

+# Or point packages/db/.env at any Postgres 15+:
+# DATABASE_URL=postgresql://… # pooled / app
+# DATABASE_URL_UNPOOLED=postgresql://… # direct — required by Prisma directUrl / migrate
+pnpm --filter @poc-plattform-kit/db exec prisma migrate deploy
+```
</code_context>
<issue_to_address>
**issue (bug_risk):** The documented live-migration path invokes `infra/migrate-db.ps1`, but that script writes only `DATABASE_URL` to `packages/db/.env` and does not retrieve `database-url-unpooled`. Prisma then fails schema loading because `schema.prisma` unconditionally evaluates `directUrl = env("DATABASE_URL_UNPOOLED")`, so `migrate deploy` and `migrate status` do not work from a fresh environment.
**Triggers:** When a fresh checkout runs the documented `pwsh ./infra/migrate-db.ps1` path without an existing `packages/db/.env` containing `DATABASE_URL_UNPOOLED`.
**Suggested fix:** Make `infra/migrate-db.ps1` retrieve and write both Key Vault secrets, or change the Prisma/migration configuration so the direct URL is optional for the migration path.
</issue_to_address>
### Comment 3
<location path="docs/db-practices.md" line_range="122" />
<code_context>
- Opaque public IDs (`cuid` / `ulid` / `uuid`) for APIs; document generation once.
- Don’t rely on enumerable identity columns as the sole public handle.
-- **Platform convention (ADR [0005](./adr/0005-entity-id-strategy.md)):** keep Prisma `@default(cuid())` for primary keys; annotate keyed/reference `String` columns with explicit native lengths instead of Prisma’s default `NVARCHAR(1000)` on SQL Server.
+- **Platform convention (ADR [0005](./adr/0005-entity-id-strategy.md)):** keep Prisma `@default(cuid())` for primary keys; annotate keyed/reference `String` columns with explicit `@db.VarChar(n)` (not Prisma’s unbounded default).
| Prisma role | Max length | Examples |
</code_context>
<issue_to_address>
**issue:** The updated database guidance says PostgreSQL `@db.VarChar(n)` is the platform convention and refers readers to ADR 0005, but ADR 0005 still states that SQL Server is current and that `@db.NVarChar(n)` will be replaced after a future Neon cutover. The referenced ADR therefore gives implementers contradictory provider and native-type instructions after this PR claims the cutover is complete.
**Triggers:** When a developer follows the new database-practices guidance to ADR 0005 while adding or sizing Prisma string fields.
**Suggested fix:** Update ADR 0005 to describe PostgreSQL as the current provider and mark its SQL Server mapping and migration discussion as historical, or link only to an updated replacement ADR.

🟡 Changes recommended
A few doc lines are internally inconsistent (e.g., “shared Neon” vs Azure Flexible Server as shared host) and one comment has visible encoding corruption that should be corrected for readability.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR updates the repo’s engineering and operational documentation to adopt PostgreSQL as the canonical Prisma provider, positioning Neon as the PoC host and Azure Database for PostgreSQL Flexible Server as the shared/always-on target, and removes Azure SQL / SQL Server defaults from agent-facing guidance.
Changes:
- Replace Azure SQL/SQL Server references with PostgreSQL + Prisma (
postgresql) across core docs and templates. - Document provider portability expectations (no Neon-only persistence APIs in domain code) and local Neon/Postgres +
pg_dump/pg_restoreguidance. - Update testing/preview guidance to reflect SQLite preview limits vs PostgreSQL-specific behavior.

Azure Database for PostgreSQL Flexible Server built-in PgBouncer port 6432 server FQDN official documentation
💡 Result:
To connect to the built-in PgBouncer in Azure Database for PostgreSQL Flexible Server, you should use the same Fully Qualified Domain Name (FQDN) as you use for your standard PostgreSQL connection, but update the port from the default 5432 to 6432 [1][2][3]. Key details regarding this configuration: - Hostname/FQDN: Use the same FQDN as your database server (e.g., myPgServer.postgres.database.azure.com) [1][2]. - Port: Specify port 6432 [1][3]. - Enabling: PgBouncer is an optional feature. You must enable it by setting the server parameter pgbouncer.enabled to true via the Azure portal or CLI [4][2][5]. No server restart is required to enable it [4][5]. - Availability: It is supported on General Purpose and Memory Optimized compute tiers [1][2][6]. It is not available on the Burstable tier [6]. - Failover Behavior: In high-availability (HA) configurations, PgBouncer runs on the primary server. Following a failover, the system automatically restarts PgBouncer on the newly promoted standby (which becomes the new primary), allowing your connection string to remain unchanged [2]. For more information, refer to the official documentation on PgBouncer in Azure Database for PostgreSQL Flexible Server [1].
