There was a problem hiding this comment.
This part of the comment needs an update, we now use a different planBuilder to delay the CTE lookup.

@cloud-fan Failures seem unrelated, same test is failing in other PRs as well. Can you check please? |

Fix parametrized identifiers not working when referencing CTEs
Why are the changes needed?
For a query:
with t1 as (select 1) select * from identifier(:cte) using cte as "t1"the resolution fails because
BindParameterscan't resolve parameters because it waits forResolveIdentifierClauseto resolveUnresolvedWithCTERelation, butResolveIdentifierClausecan't resolveUnresolvedWithCTERelationuntil allNamedParametersin the plan are resolved.Instead of delaying CTE resolution with
UnresolvedWithCTERelation, we can remove node entirely and delay the resolution by keeping the originalPlanWithUnresolvedIdentifierand moving the CTE resolution to itsplanBuilder.Does this PR introduce any user-facing change?
No
