"UPDATE ... FROM" generated "ERROR: variable not found in subplan
target lists". I've added some workaround in add_vars_to_targetlist:
- if it is an "after" - simple change var->varno to base RTE (it should
always exists, the value is temporary, it will change to OUTER_VAR)
- if it is a "before" - add to targetlist new var independently from
rel->attr_needed[attno].
Additionally I've change build_joinrel_tlist to ignore any "BEFORE"
RTEs. The regression tests are updated.
