PostgreSQL UUID Generator — gen_random_uuid Helper

RFC 4122 v4 UUID generation — proxies uuid-generator for PostgreSQL uuid column defaults

How to Use This Tool

  1. Click generate on proxied uuid-generator widget.
  2. Client-side crypto.getRandomValues produces v4 UUID.
  3. Copy lowercase hyphenated UUID for SQL and application use.
  4. Cast string to uuid type in PostgreSQL with ::uuid suffix.
  5. Use gen_random_uuid() in SQL for server-side generation.
  6. Regenerate for additional test rows as needed.

About This Tool

PostgreSQL uuid columns with gen_random_uuid() defaults and application-inserted primary keys both need RFC 4122 identifiers — developers search PostgreSQL-specific UUID generator pages expecting copy-ready v4 strings compatible with uuid type casts. VSPIC PostgreSQL UUID generator proxies uuid-generator per missing-tools-handlers.generated.ts — type proxy, slug uuid-generator — embedding client-side v4 generation via crypto.getRandomValues with one-click copy.

This page frames PostgreSQL SEO vocabulary while the proxied widget matches uuid-generator exactly. Generate IDs for seed scripts, migration test rows, and ORM fixtures — then cast with ::uuid in SQL or bind as UUID parameter in drivers. For server-side generation, prefer gen_random_uuid() inside INSERT statements.

Common use cases

  • Inspect HTTP headers and user-agent strings
  • Analyze email headers for phishing investigation
  • Generate strong passwords for staging environments

Why use VSPIC for ?

  • Full uuid-generator proxy — not a stub placeholder.
  • Client-side generation — IDs never uploaded on generate.
  • RFC 4122 v4 compatible with PostgreSQL uuid type.
  • One-click copy for seed SQL and migration fixtures.
  • Works offline after initial page load.
  • Pairs with mongodb-objectid-generator for cross-database dev IDs.

PostgreSQL uuid type

Native uuid type stores 128-bit identifiers efficiently with index support. Cast string literals with ::uuid or use JDBC setObject with UUID class.

Proxy to uuid-generator

postgresql-uuid-generator maps to type proxy, slug uuid-generator. Same React widget as canonical uuid-generator page.

gen_random_uuid versus browser generate

Server-side gen_random_uuid() inside INSERT guarantees database-origin IDs and avoids client clock dependency. Browser tool suits offline seed script authoring.

Seed script workflow

Generate UUIDs here, paste into INSERT VALUES list, run migration against staging before production.

Relationship to uuid-generator

Identical proxy target. postgresql-uuid-generator emphasizes PostgreSQL SEO; uuid-generator general vocabulary.

Relationship to mongodb-objectid-generator

MongoDB ObjectId is different format — 24 hex chars. Use appropriate generator per database engine.

Version 4 random UUID

v4 uses random bits — no MAC address leakage unlike legacy v1. Preferred for public-facing identifiers.

Client-side privacy

Generated UUIDs stay in browser until you copy. No server round-trip for generation.

ORM binding

Prisma, Drizzle, and Sequelize accept UUID strings for uuid columns — match driver type mapping in schema.

Important notes & limitations

  • Browser-generated UUIDs suit dev seeds — production may prefer gen_random_uuid().
  • Proxies uuid-generator — no PostgreSQL-specific version 1 MAC UUID.
  • Does not run INSERT or validate unique constraint conflicts.
  • Single generate action — bulk seed lists need script loop.
  • uuid type requires PostgreSQL extension or built-in gen_random_uuid in PG13+.
