Thanks.
I'm getting an assertion failure with this statement:
CREATE TABLE foo (id int4);
MERGE into foo t
USING (select id FROM generate_series(1,5) id) AS s
ON t.id = s.id
WHEN NOT MATCHED THEN INSERT (id) VALUES (s.id);
TRAP: FailedAssertion("!(ActiveSnapshotSet())", File: "postgres.c",
Line: 749)
That's easily fixed - you need to add "case T_MergeStmt" to the list of
optimizable command types in analyze_requires_snapshot() function.
Unfortunately that doesn't get you far, the query then trips another
assertion:
TRAP: FailedAssertion("!(list_length(resultRelations) ==
list_length(subplans))", File: "createplan.c", Line: 3929)
