P {margin-top:0;margin-bottom:0;}Hi,
I have a Postgresql 11 and Slony 2.2.7 setup with one master and multiple slave nodes. On one of the slaves I want a user defined trigger to fire on insert. The trigger fires a notify function.
Now to the problem.
If I create the trigger it looks like it is enabled on the slave but it do not fire.
CREATE TRIGGER <trigger_name>
AFTER INSERT
ON <table_name>
FOR EACH ROW
EXECUTE PROCEDURE <function_name>;
If i try to enable it explicit with
ALTER TABLE <table_name>
ENABLE ALWAYS TRIGGER <trigger_name>;
or
ALTER TABLE <table_name>
ENABLE REPLICA TRIGGER <trigger_name>;
and then look at the table definition the trigger is disabled.
How? can you show the output of \d ? or pg_dump -x --schema-only -t <table_name> ?
Is this expected behavior in slony?
I understand that this may be tricky in replication context and that the default behavior is that triggers on slaves are disabled.
We have plans to move to logical replication which should solve this I assume, but it does not fit the schedule at the moment.
