I was running a sample of roachtests on my PR (#107548) and noticed that the unoptimized-query-oracle/disable-rules=all/rand-tables test failed due to an assertion failure in the cockroach node:

E230726 03:19:06.241395 2499 sql/sqltelemetry/report.go:57 ⋮ [T1,n1,client=35.230.180.232:57860,hostnossl,user=root] 6246 +building declarative schema change targets for CREATE FUNCTION: ReturnType called on TypedExpr with empty typeAnnotation. Was the underlying Expr type-checked before asserting a type of TypedExpr?

I don't think this is related to the diff on my PR (mostly changes in the roachtest monitor), so I'm opening a separate issue for this. Artifacts can be found at:
