Steps to duplicate

ALTER USER {user} SET default_transaction_isolation TO 'repeatable read';

psql -U {user}
SHOW default_transaction_isolation;
with correctly show  'repeatable read'

psql         (default with postgres)
set role {user};
SHOW default_transaction_isolation;
will incorrectly show  postgres's value?
'read committed'

Thanks for the Awesome work.

"SET ROLE does not process session variables as specified by the
role's ALTER ROLE settings; this only happens during login."
