Perhaps the precision in case of a base table column with NUMERIC/DECIMAL type is too small

Copy SQL

SELECT table_schema, table_name, column_name, data_type, numeric_precision, numeric_scale
FROM INFORMATION_SCHEMA.columns
WHERE data_type ='numeric' 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)
AND numeric_precision=numeric_scale
ORDER BY table_schema, table_name, ordinal_position;
