Subject: Update "usename" in pg_user

Message-ID: <PR3PR04MB73409EB3F2695DA61418F784D6B2A@PR3PR04MB7340.eurprd04.prod.outlook.com> (raw)
Hi,
the last time i wrote a SQL command is about 20 years ago.
So I'm asking for your advice.
I have a DB which is accessed by ~ 40 users.
The users are in pg_user and authenticated with LDAP.
Due to change of the LDAP server I need to modify the username now.
From firstname.lastname to firstname.lastname@helmholtz-munich.de.
I tried the following (just for one user to test it):
update pg_user set usename = 'usename@helmholtz-munich.de' where usename = 'dorota.germann';
It didn't work. I got this message (unfortunately in german):
postgres=# update pg_user set usename = 'usename@helmholtz-munich.de' where usename = 'dorota.germann';
FEHLER: kann Sicht »pg_shadow« nicht aktualisieren
DETAIL: Sichten, die nicht aus einer einzigen Tabelle oder Sicht lesen, sind nicht automatisch aktualisierbar.
HINT: Um Aktualisieren der Sicht zu ermöglichen, richten Sie einen INSTEAD OF UPDATE Trigger oder eine ON UPDATE DO INSTEAD Regel ohne Bedingung ein.
Any idea ?
Bernd
