[GitHub] incubator-trafodion pull request: [TRAFODION-1867] Allow parallel ...

[TRAFODION-1867] Allow parallel plans for non-partitioned tables in U…
…PD STATS.
The problem is for large non-partitioned tables, UPDATE STATS will do a series of SELECTs to compute statistics for sets of columns. The plans for these SELECTs are presently forced to be serial for non-partitioned tables as a workaround for a long-ago compiler bug which seems to have been fixed. It's time to remove this workaround and thereby speed up UPDATE STATS.
