OK, that was less painful than I feared.  makeWholeRowVar has
several different special cases for RTE_FUNCTION, but most of them
don't bear on this problem, because we wouldn't have applied inlining
when they did.  It seems sufficient to fetch pg_type.typrelid for
the function's nominal return type and store that if it's not 0.

Patches for HEAD and v15 attached.  I haven't checked other branches
but I expect the deltas won't be big.

  1. Repair commits 317aba70e et al for -DWRITE_READ_PARSE_PLAN_TREES.

  2. Build whole-row Vars the same way during parsing and planning.

  3. Preserve RangeTblEntry.relid when expanding a view RTE.

  4. Fix incorrect non-strict join recheck in MERGE WHEN NOT MATCHED BY SOURCE.
