32.10. column_privileges

The view column_privileges identifies all privileges granted on columns to a currently enabled role or by a currently enabled role. There is one row for each combination of column, grantor, and grantee.

In PostgreSQL, you can only grant privileges on entire tables, not individual columns. Therefore, this view contains the same information as table_privileges, just represented through one row for each column in each appropriate table, but it only covers privilege types where column granularity is possible: SELECT, INSERT, UPDATE, REFERENCES. If you want to make your applications fit for possible future developments, it is generally the right choice to use this view instead of table_privileges if one of those privilege types is concerned.
