[COMMITTERS] pgsql: Fix problems with the "role" GUC and parallel query. - Mailing list pgsql-committers

Fix problems with the "role" GUC and parallel query.

Without this fix, dropping a role can sometimes result in parallel
query failures in sessions that have used "SET ROLE" to assume the
dropped role, even if that setting isn't active any more.

Report by Pavan Deolasee.  Patch by Amit Kapila, reviewed by me.
