I am working on a date-based partitioning framework and I would really like
to have a single function that could be used as trigger for any table that
needs to be partitioned by day. I am working in a rails environment, so
every table has a created_at datetime field.
I created my generic function:

PostgreSQL folks!
We are looking for the next big thing. Actually, it's a bit smaller: a
new design for mugs. So far we had big blue elephants, small blue
elephants, frosty elephants, white SQL code on black mugs ... Now it's
time to design something new.
What's in for you? Fame, of course

Maintaining an unused index still requires its blocks to be read.

Well, from a relational theory point of view, a variable which
stores a relation is what a table *is*. PostgreSQL attempts to
store data for temporary tables in RAM and spill them to disk only
as needed. So IMO the response su

Thanks.
how about the case as follows?
idx_scan = 0 and idx_tup_read = 0 and idx_tup_fetch = 0, but
idx_blks_read is not 0 and idx_blks_hit is not 0
?

No, it isn't --- the tuple is being modified by the ALTER command.

I narrowed the issue down to trying to select from a view being created in
the same extension, like so:
create or replace view av as select 1 as a;
create table ax as select * from av;
Even just selecting from the view after creating it causes the error so
it's the access to the view that's the i

Hi,
Below query can be handy to find unused indexes.
select indexrelname from pg_stat_user_indexes where idx_scan = 0 and
idx_tup_read = 0 and idx_tup_fetch = 0 ;
Hope it helps.
