PostgreSQL DDL Generator

Why not just write SQL by hand?

With 10 tables it's fine. With 68 tables, 69 foreign keys, and a mix of enums, domains, views, functions, and RLS policies — the order matters. One misplaced CREATE and your script fails. PgDesigner resolves all of this automatically.

15-phase dependency sort

DDL is generated in the correct execution order — not alphabetical, but topological. Each phase handles a specific object type, so foreign keys never reference tables that don't exist yet.

Foreign keys are always emitted as ALTER TABLE after all tables are created. Materialized views are sorted by their own inter-dependencies. Identity columns use inline GENERATED ALWAYS AS IDENTITY — not separate ALTER statements like pg_dump.

99.7% round-trip fidelity — proven on 630+ tables

We don't just claim accuracy — we test it. The full round-trip cycle:

SQL → PGD → DDL → PostgreSQL → pg_dump → PGD → diff = zero changes

Tested on 6 real databases: Chinook, Northwind, Pagila, Airlines, AdventureWorks, and a synthetic 120+ table schema. All are included as sample projects.

CLI — generate from the terminal

pgdesigner generate schema.pgd
pgdesigner generate schema.pgd > schema.sql
pgdesigner generate schema.pgd --table users

Pipe it into psql, commit it to git, or use it in your CI pipeline. Zero dependencies — single binary.

UI — preview before you generate

Press Ctrl+G to open the Generate DDL dialog. You get a full SQL preview with syntax highlighting, copy to clipboard, and save to file — all before a single statement hits your database.
