Stopgap patch for problem with cursors using hash joins: an ABORT
would cause two attempts to delete the hashtable portal, one fromquery shutdown and one from portalmem.c. Fix by making hash portalsbe treated as 'special' portal names, so that CollectNamedPortalswill not think it should delete them. This code is in need ofcomplete rewrite (and is already largely rewritten in currentsources), but still need to put a finger in the dike for 7.0.*.
