Well, I certainly think all of these represent bugs:
3 | ERROR: plan should not reference subplan's variable
2 | ERROR: failed to assign all NestLoopParams to plan nodes
These appear to be related. The following query produces the former,
but if you replace the very last reference of provider with the literal
'bar', it raises the latter error.
Fixed that, thanks for the test case!
I haven't seen the former since your commit, but there recently were
some instances of the latter. The attached queries all throw the error
against master at 8752bbb.
