Обсуждение: age of statistics

Is there a way to query the database to find out how old the current
table statistics are?  That is, when the ANALYZE command was last run
on a given table?  It seems like there ought to be a table somewhere
in pg_catalog I can't find it in the PostgreSQL Administrator
documentation, nor by searching google.

Thanks,

Whoops -- that should say:

It seems like there ought to be a table somewhere in pg_catalog with a
date in it, but I can't find it.  I've poked around with 'select
tablename from pg_tables' with no luck, nor can I find it in the
PostgreSQL Administrator documentation, nor by searching google. :-/

Thanks,

That's because there isn't one ...
