Goal Find base table columns that have the same name as the domain name or the data type name of the column. The names may have different uppercase/lowercase characters. Columns, domains, and types are different concepts in SQL and perhaps it is better to use different names in case of these.
Type Problem detection (Each row in the result could represent a flaw in the design)
Reliability Low (Many false-positive results)
License MIT (opens in new tab)
Fixing Suggestion Rename the column or domain. Use a prefix in the domain name.
Data Source INFORMATION_SCHEMA only
SQL Query 
SELECT table_schema, table_name, column_name, data_type, domain_name, domain_schema
FROM INFORMATION_SCHEMA.columns 
WHERE (table_schema, table_name) IN (SELECT table_schema, table_name
FROM INFORMATION_SCHEMA.tables WHERE table_type='BASE TABLE')
AND (column_name ILIKE domain_name OR column_name ILIKE data_type)
AND table_schema NOT IN (SELECT schema_name
FROM INFORMATION_SCHEMA.schemata
WHERE schema_name<>'public' AND
schema_owner='postgres' AND schema_name IS NOT NULL)
ORDER BY table_schema, table_name, ordinal_position;
