[HACKERS] road.thepath no longer in pg_stats?
Hi, I just noticed that the road.thepath column in the regression database is no longer in pg_stats for some reason after ANALYZE, so the example in section 14.2 in the docs (Statistics Used by the Planner) is now wrong. What I'm trying to do is replace that exceedingly wide output with something along these lines instead: SELECT attname, n_distinct, array_to_string(most_common_vals, E'\n') as most_common_vals FROM pg_stats WHERE tablename = 'road'; but this is failing because of missing values for that column, as well as there being two rows for the column that is there (stainherint=f producing the other one) -- Alvaro Herrerahttp://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

It's an old example :-( ... a quick check shows no version since 7.3 generates stats for that column. but this is failing because of missing values for that column, as well as there being two rows for the column that is there (stainherint=f producing the other one) Two rows are expected now, since that table has children --- there should be one for inherited = t and one for inherited = f. Probably wouldn't hurt to explain that explicitly here. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
