The naming of BOOLEAN columns must be consistent. For the better readability the names of such columns could have prefix "is_" (in English) or "on_" (in Estonian)
Notes
The query considers base tables, views, foreign tables, and materialized views, i.e, snapshots. Data about materialized views has to be read directly from the system catalog base tables because information_schema views do not provide information about these.
Type
General (Overview of some aspect of the database.)
Use a consistent naming style and rename the column if needed.
Data Source
INFORMATION_SCHEMA+system catalog
