I've have a look to the plan with pgadmin, and I think the problem is
rather here :
-> Sort (cost=4997.11..4997.11 rows=1 width=69) (actual
time=27.427..28.896 rows=7359 loops=1)
Sort Key: amendment.id
Sort Method: quicksort Memory: 1227kB
-> Nested Loop (cost=183.44..4997.10 rows=1 width=69) (actual
time=1.115..24.616 rows=7359 loops=1)
-> Nested Loop (cost=183.15..4996.59 rows=1 width=49)
(actual time=1.107..9.091 rows=7360 loops=1)
-> Index Scan using uk_3b1y5vw9gmh7u3jj8aa2uy0b9 on
contact_partner businessprovider (cost=0.42..8.44 rows=1 width=13)
(actual time=0.010..0.010 rows=1 loops=1)
Index Cond: ((business_provider_code)::text =
'BRZH'::text)
-> Bitmap Heap Scan on contract_contract_line
contractline (cost=182.73..4907.58 rows=8057 width=52) (actual
time=1.086..5.231 rows=7360 loops=1)
Recheck Cond: (business_provider_partner =
businessprovider.id)
Heap Blocks: exact=3586
-> Bitmap Index Scan on
contract_contract_line_business_provider_partner_idx
(cost=0.00..180.72 rows=8057 width=0) (actual time=0.655..0.655
rows=7360 loops=1)
Index Cond: (business_provider_partner =
businessprovider.id)
-> Index Scan using contract_amendment_pkey on
contract_amendment amendment (cost=0.29..0.50 rows=1 width=28)
(actual time=0.001..0.002 rows=1 loops=7360)
Index Cond: (id = contractline.amendment)
The bitmap scan on contract_contract_line is good (8057 vs 7360 rows),
and so is the index scan (1 row), but the JOIN with "contact_partner
businessProvider" should give the 8057 rows from the bitmap scan,
shouldn't it ?
