Goal Find base table columns that do not have uuid type but the name of the column refers to the possibility that the values in the column are uuid's.
Type Problem detection (Each row in the result could represent a flaw in the design)
Reliability Low (Many false-positive results)
License MIT License
Fixing Suggestion Change the data type of the column.
Data Source INFORMATION_SCHEMA only
SQL Query
SELECT table_schema, table_name, column_name
FROM INFORMATION_SCHEMA.columns
WHERE data_type<>'uuid' 
AND column_name~*'uuid'
AND (table_schema, table_name) IN (SELECT table_schema, table_name
FROM INFORMATION_SCHEMA.tables WHERE table_type='BASE TABLE') 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;
