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.
