PgDesigner validates your schema against 66 built-in lint rules grouped into three severity levels. Errors block DDL generation. Warnings indicate valid but likely problematic constructs. Info rules are suggestions for best practices. Rules marked as fixable can be resolved automatically using the autofix action.
32 rules — block DDL generation.
