Domain name and type name are the same

Query goal:

Use different names to avoid confusion.

Query type:

Problem detection (Each row in the result could represent a flaw in the design)

Query reliability:

High (Few or no false-positive results)

Query license:

MIT License

Fixing suggestion:

Rename the domain so that its name is not the same as the type name.

Data source:

INFORMATION_SCHEMA+system catalog
