Goal Use different names to avoid confusion.
Type Problem detection (Each row in the result could represent a flaw in the design)
Reliability High (Few or no false-positive results)
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
SQL Query
WITH domain_names AS (SELECT domain_schema, domain_name
FROM information_schema.domains
WHERE domain_schema NOT IN (SELECT schema_name
FROM INFORMATION_SCHEMA.schemata
WHERE schema_name<>'public' AND
schema_owner='postgres' AND schema_name IS NOT NULL)),
type_names AS (SELECT nspname AS type_schema, typname AS type_name

WHERE typtype<>'d')
SELECT domain_schema, domain_name, type_schema, type_name
FROM domain_names, type_names
WHERE lower(domain_name)=lower(type_name)
ORDER BY domain_schema, domain_name;
