Hi, ALL,
In my code I'm running following:
queries.push_back( L"CREATE FUNCTION
__watch_schema_changes() RETURNS event_trigger LANGUAGE plpgsql AS $$
BEGIN NOTIFY tg_tag; END; $$;" );
queries.push_back( L"CREATE EVENT TRIGGER
schema_change_notify ON ddl_command_end WHEN TAG IN(\'CREATE TABLE\',
\'ALTER TABLE\', \'DROP TABLE\', \'CREATE INDEX\', \'DROP INDEX\')
EXECUTE PROCEDURE __watch_schema_changes();" );
My questions are:
1 Is there a better way to get notification about CREATE/ALTER/DROP TABLE?
An alternate solution:
https://www.pgaudit.org/
Whether it is better or not is something you will need to decide.
2. How do I receive notification abut the event with the object name?
Use information from here?:
https://www.postgresql.org/docs/current/functions-event-triggers.html#PG-EVENT-TRIGGER-DDL-COMMAND-END-FUNCTIONS
Thx for the link
So basically all I need to do is to call
SELECT pg_event_trigger_ddl_commands ()
And then unpack the information it returns.
right?
In both ODBC amd libpq interfaces?
It is not about the interface it is about, from link above:
"pg_event_trigger_ddl_commands returns a list of DDL commands executed
by each user action, when invoked in a function attached to a
ddl_command_end event trigger."
Thank you.
Thank you.
