No, I haven't. I can have a look later, thanks.

metadata_03
(cost=0.00..5869.24 rows=579474 width=0) (actual
time=222.724..222.724 rows=557834 loops=1)"
"Index Cond: ((name)::text = 'product_title'::text)"
"Buffers: shared read=3953"
it can be seen that it uses idx_product_metadata_03 which is on (name,
value). Shouldn't it use index_product_metadata_02 which is on
(product_id, name)?
Or is there another reason why this query is so slow?
I have changed some of the default settings of Postgres as follows:
random_page_cost = 1.4
cpu_index_tuple_cost = 0.1
effective_cache_size = 256MB
work_mem = 300MB
If you need any other information, let me know.
Thanks in advance!
With regards,
