Exactly, I want to drop unused tables, views, etc..., I am writing now a shell script to handle this issue by analyzing the log files. If you have suggestions and comments I will be glade to hear it.

I do not know what your criteria is for dropping things. But I would be very sure that something is no longer used. For example, some tables are not used but once a quarter or once a year. And the same is true with views and procedures. But that would also depend on the type of data like accounting or inventory verses customer. Just some thoughts.

Hello Guys,
This is a simple way to check if there is no activity on the table,
SELECT relname,seq_tup_read,idx_tup_fetch FROM pg_stat_user_tables WHERE (idx_tup_fetch + seq_tup_read)= 0;
Is there is any way to make similar checks on views
Regards

Hello,
I am trying to drop deprecated tables, views, procedures from an existing database, I am checking the pg_stat_user_tables view to check if the tables are accessed recently also to check live tuples. For deprecated views and procedures, I am wondering How can I do that, for example suppose the table is used and there is a view defined using this table but no one is using it. Is there is away to check the views statistics.
