Business-critical applications require continuous monitoring and adjustment of query plans. The problem hardens due the fact that actual resources consumption by query execution could differ significantly with slight changes of the query plan cost. Thus, there is a permanent risk of bad plan selection and overall system performance degradation after collecting new statistics. DBAs want to protect themselves from this risk by freezing plans of particular most critical queries.
Temporary tables are often being used. Their performance could be increased if they are removed from system catalog. Also it is attractive to allow using temporary tables on read-only standbys.
