RES: RES: session_user different from current_user after normal login

Could it be the role=group_read_only? The fact that user1 is a member of group_read_only is changing current_user variable?
I’m using a clean psql docker container everytime I need to connect to the database, so, I don’t think it’s related to psql.

\drds
List of settings
Role | Database | Settings

user1 | mydb | role=group_read_only
rdsadmin | rdsadmin | log_min_messages=panic
rdsadmin | | TimeZone=utc +
| | log_statement=all +
| | log_min_error_statement=debug5 +
| | log_min_messages=panic +

Thanks.

Murillo.

I believe it's possible to do ALTER USER ... SET ROLE ... or
ALTER DATABASE ... SET ROLE ..., which'd produce this sort of
effect. psql's "\drds" metacommand would help remind you of
any such settings. I can't offhand think of any other server-side
configuration that would do it.
