Tighten up application of parallel mode checks. Commit 924bcf4f16d54c55310b28f77686608684734f42 failed to enforce parallel mode checks during the commit of a parallel worker, because we exited parallel mode prior to ending the transaction so that we could pop the active snapshot. Re-establish parallel mode during parallel worker commit. Without this, it's far too easy for unsafe actions during the pre-commit sequence to crash the server instead of hitting the error checks as intended.
Just to be extra paranoid, adjust a couple of the sanity checks in xact.c to check not only IsInParallelMode() but also IsParallelWorker().
