I have to insert several IF statements in the "IF FOUND" one.
I wont do it one time, I will insert them one by one.

I cannot stop too much long the PG server (a /etc/init.d restart time
is OK, more is not)

Dumping and the restoring is not possible because of too long downtime.

DELETing CREATing the function is not possible because of dependency.

When looking at the help, '\h' has no REPLACE FUNCTION.
Only ALTER FUNCTION

How to manage it?

You're probably looking for CREATE OR REPLACE.

Write it exactly as you have above, but replace the first line with:

CREATE OR REPLACE FUNCTION f_active_client(character varying)
