Addressed the following issues from the review of the patch:
1. The PERSISTENT FOR clause of the ANALYZE command overrides
the setting of the system variable use_stat_tables:
with this clause ANALYZE unconditionally collects persistent
statistics.
2. ANALYZE collects persistent statistics only for tables of
the USER category. So it never collects persistent statistics
for system tables.
