Hi,
I'm having difficulty in trying to understand the value I should use for
`pages_in_range` when creating a BRIN index. I have data coming in, nearly 3-4
rows per second with an ever increasing `created` timestamp. Perfect for a
BRIN index to save on space :-).
I gathered some data (at time of query) on the table I'm interested in:
Size (bytes): 16130588672
Pages: 1969066
Rows: 48215073
Rows/Page: 24
At the moment, the column I'm indexing on, created, has a BTREE index on it,
and it's over 2GB in size!
What would I need to do to go about choosing an appropriate value for
pages_in_range?
Lastly, is it necessary to run a `vacuum analyse freeze` before/after
index creation?
Thank you!
