Done. I figured reviews would be unlikely to show up soon for a dsa.c patch, but of course post-commit review is very welcome. I thought it best to have this fix in REL_11_STABLE being tested for as long as possible before any potential RC1 tag, especially if Tomas plans to continue his "big join" testing on that branch. -- Thomas Munro http://www.enterprisedb.com
