The view <literal>column_privileges</literal> identifies all
|
||||||
|
privileges granted on columns to the current user or by the current
|
||||||
|
user. 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 <literal>table_privileges</literal>, just
|
||||||
|
represented through one row for each column in each appropriate
|
||||||
|
table. But if you want to make your applications fit for possible
|
||||||
|
future developements, it is generally the right choice to use this
|
||||||
|
view instead of <literal>table_privileges</literal>.

|
Triggers in PostgreSQL have two incompatibilities with the SQL
|
||||||
|
standard that affect the representation in the information schema.
|
||||||
|
First, trigger names are local to the table in PostgreSQL, rather
|
||||||
|
than independent schema objects. Therefore there may be duplicate
|
||||||
|
trigger names defined in one schema, as long as they belong to
|
||||||
|
different tables. (<literal>trigger_catalog</literal> and
|
||||||
|
<literal>trigger_schema</literal> are really the values pertaining
|
||||||
|
to the table that the trigger is defined on.) Second, triggers can
|
||||||
|
be defined to fire on multiple events in PostgreSQL (e.g.,
|
||||||
|
<literal>ON INSERT OR UPDATE</literal>), whereas the SQL standard
|
||||||
|
only allows one. If a trigger is defined to fire on multiple
|
||||||
|
events, it is represented as multiple rows in the information
|
||||||
|
schema, one for each type of event. As a consequence of these two
|
||||||
|
issues, the primary key of the view <literal>triggers</literal> is
|
||||||
|
really <literal>(trigger_catalog, trigger_schema, trigger_name,
|
||||||
|
event_object_name, event_manipulation)</literal> instead of
|
||||||
|
<literal>(trigger_catalog, trigger_schema, trigger_name)</literal>,
|
||||||
|
which is what the SQL standard specifies. Nonetheless, if you
|
||||||
|
define your triggers in a manner that conforms with the SQL
|
||||||
|
standard (trigger names unique in the schema and only one event
|
||||||
|
type per trigger), this will not affect you.
