Обсуждение: Occupation bloc in pages of table

Hello,


I  see in the documentation that we can obtain the number of pages for a table with the view named pg_class.

I would want if it is possible for each pages of a table to have the occupation of blocs in percentage in order to see
ifthe page is good full or not. 

I don’t find anything in the doc and the archive.

Best regards,


Sorry for my english

There is not any magic way of getting that information, but you could
modify contrib/pgstattuple to produce such a report.
