You can reconfigure the parameters of a session used to establish a connection with your AnalyticDB for PostgreSQL instance. For more information, see the Greenplum documentation.
The statement used to reconfigure a parameter is as follows:
ALTER ROLE <The username of your account> SET <The name of the parameter> = <The new
value of the parameter>. This statement only takes effect on the specified user.
If you want to reconfigure instance-level parameters, submit a ticket or join the AnalyticDB for PostgreSQL technical support group on DingTalk. For more information, see How do I obtain technical details about AnalyticDB for PostgreSQL?
