UPDATE was listed twice and DELETE was omitted, replace one UPDATE
with DELETE instead.

MERGE is a multiple-table, multiple-action command: It specifies a target
table and a source relation, and can contain multiple WHEN MATCHED and
WHEN NOT MATCHED clauses, each of which specifies one UPDATE, INSERT,
UPDATE, or DO NOTHING actions. The target table is modified by MERGE,
DELETE, or DO NOTHING actions. The target table is modified by MERGE,
and the source relation supplies additional data for the actions. Each action
optionally specifies a qualifying expression that is evaluated for each tuple.
