Hi Depesz,
Sorry , I didn't mention it clearly. We are using these triggers for audit purposes.

Triggers calls a procedure to insert username,machine.IPAddress into LogonTime in an audit table.
We also have a trigger that gets fired BEFORE ALTER OR CREATE OR DROP on schema that will audit the user details in the audit table.

Any alternative solution in Postgres is welcome.

Thanks in advance.

Regards,
Aditya.

What did it do?

Please note that not everyone knowing Pg knows Oracle.

I can imagine that trigger after logon means that p1 procedure will be
called after user successfully logs in, but what does the "for each row"
part mean?

In PG, there are no login triggers. And, in any case, noone logs to
"schema".

Best regards,

depesz
