Goal Find the columns where the name reffers to the possibility that the column contains phone numbers but the type of the column is not VARCHAR or TEXT.
Notes The query considers both column names in English and Estonian.
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 Change the type of the column to VARCHAR(n) or TEXT. In the latter case add an additional constraint to the maximum value length permitted in the column.
Data Source INFORMATION_SCHEMA only
SQL Query

FROM INFORMATION_SCHEMA.columns
WHERE data_type!~'(character varying|text)' 
AND column_name~*'(phone|telef)'
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;
