Docs: modified analyzedb clean up behavior after changes
previous <cmdname>analyzedb</cmdname> operation. The snapshots of table metadata are stored
as state files in the directory
<codeph>db_analyze/&lt;<varname>db_name</varname>>/&lt;<varname>timestamp</varname>></codeph>
- in the Greenplum Database coordinator data directory. </p>The utility does not automatically
- remove old snapshot information. Over time, the snapshots can consume a large amount of disk
- space. To recover disk space, you can keep the most recent snapshot information and remove the
- older snapshots. You can also specify the <codeph>--clean_last</codeph> or
- <codeph>--clean_all</codeph> option to remove state files generated by
- <cmdname>analyzedb</cmdname>. <p>If you do not specify a table, set of tables, or schema,
- the <cmdname>analyzedb</cmdname> utility collects the statistics as needed on all system
- catalog tables and user-defined tables in the database. </p><p>External tables are not
