https://www.postgresql.org/docs/current/static/view-pg-stats.html will give you the idea of data distribution for column. It is populated by autovacuum based on your settings. Or manual runs.
Also yo can run queries like
select max(c), min(c), avg(c) from tnameto get exact data the is of interest for you.To do that I would recommend using
psql- it is free and extremely handy for querying Postgres. Also you can easilycronpsql -c "your select here"to format any report by your needs.You can save profiles and data either to files or database. It can be interactive and scripted. It works with local and remote databases. You can easily mix SQL with bash or any other scripting language variables.
All this (and much much more) cool features you will find with psql. Documentation is here. You don't need to download it if you already have Postgres client - it is part of the package.
