  1. Is there a way to delete a specific column level stats/histogram.  The following approach does not work.

 

alter table abc alter column bg_org_partner set statistics 0;

analyze   abc;

 

select *

FROM pg_stats where tablename in ('abc' ) and attname = 'bg_org_partner';

 

the most_common_vals remain and most_common_freqs remain the same.

 

  1. Any other ways or workaround such as wiping out a specific table level stat, then restore the stats but minus 1 column.  And the future vacuum analyze/analyze will not be updating that specific column stat. 

 

Thank you
