This might work for sending an email, but not very useful if I want to do something in the database.
For example, one very common use of logon triggers in other databases is to look at various connection parameters (like
usernameor source IP) and enable sql logging or debugging for only certain cases (not always doing the same thing for a
particularuser). Another common use case is to do something like running plpgsql or manipulating data in db tables -
butagain looking at some combination of things at a database level to make a decision about what to do; for example the
applicationitself might enable or disable certain behaviors by setting values in a configuration table.
I’m still trying to work out the best approach for solving these sorts of use cases in current versions of
PostgreSQL...I’m curious how others are solving this?
