Hi hackers, While testing parallel hash join today, I saw a couple of errors like this:
2017-12-26 23:34:37.402 NZDT [13082] ERROR: cannot create temporary subdirectory "base/pgsql_tmp/pgsql_tmp13080.0.sharedfileset": File exists There is a thinko in PathNameCreateTemporaryDir(), a new function added in commit dc6c4c9d. It was designed to tolerate directories existing already but forgot to handle it in the third mkdir call, so it fails with unlucky timing. Please see attached. -- Thomas Munro http://www.enterprisedb.com
