I updated statistics for tables in my database with the statement
analyze table 'TABLE_NAME' compute statistics for all columns.
With some disappointment I noted that some fields, like EMPTY_BLOCKS, AVG_SPACE where not updated. I deleted the statistics with the statement analyze table 'TABLE_NAME' delete statistics and, afterwards, I am no more able to recreate the statistics. Has anyone any hints?
Moreover how can I update the statistics for EMPTY_BLOCKS and AVG_SPACE?
Thanks.
