I think the case provided by Ashutosh was initially correct, and nothing
needs to change. Look at the similar case:
EXPLAIN SELECT x,y FROM (
SELECT oid,relname FROM pg_class WHERE relname = 'pg_index') AS
c(x,y) WHERE c.y = 'pg_index';
QUERY PLAN
--------------------------------------------------------------------------------------------
Index Scan using pg_class_relname_nsp_index on pg_class
(cost=0.27..8.29 rows=1 width=68)
Index Cond: (relname = 'pg_index'::name)
(2 rows)
I don't see any reference to the alias c(x,y) in this explain.
Similarly, the flattened VALUES clause shouldn't be referenced under the
alias t(a,b).
