Find base table columns that name refers to the possibility that these are used to register file/web addresses. Find the columns where the type refers to the possibility that values in the column are actual files.
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)
If you want to store the address of a file, then the column type should be varchar(n), not bytea or oid. Change the data type of the column or the name of the column.

AND table_schema NOT IN (SELECT schema_name
