feat(codegen): add PostgreSQL schema support and fix custom primary-key generation#10
Merged
Conversation
Add dialect-aware code generation with a PostgreSQL path in the codegen entrypoint. Extend SQL parsing, type mapping, and primary key handling for a documented minimal PostgreSQL subset while keeping MySQL coverage under tests. Update repository generation to use parsed primary key names and types instead of hard-coded id assumptions; risk is limited to the supported PostgreSQL scope.
Document the postgres dialect flag, supported scope, and current limitations in the codegen README files. Add a runnable PostgreSQL sample schema so users can verify the new dialect path locally. Record follow-up TODO items for generated output snippets and future PostgreSQL coverage such as COMMENT ON and array types.
…e-level PK typing Update model codegen to return a typed zero value in Create() error paths instead of numeric literal 0. Recompute field Go type and IDType when a table-level PRIMARY KEY marks a previously nullable column as non-null. Add regression tests for PostgreSQL UUID/string primary keys and table-level PK declarations without explicit NOT NULL to prevent compile/type regressions.
