我在Odoo数据库中有大约30K的帐户记录，甚至列出这些帐户也需要很长时间。分析查询日志，我发现这些查询需要很长时间才能完成（大约3000毫秒）......
SELECT "account_account".id FROM "account_account"
WHERE (("account_account"."active" = true)
AND ("account_account"."parent_id" in

任何机构都有任何想法调整查询或数据库设置？ 目前使用pgtune的postgres.conf设置如下：
default_statistics_target = 50 # pgtune wizard 2016-03-24
maintenance_work_mem = 120MB # pgtune wizard 2016-03-24
constraint_exclusion = on # pgtune wizard 2016-03-24
checkpoint_completion_target = 0.9 # pgtune wizard 2016-03-24
effective_cache_size = 1408MB # pgtune wizard 2016-03-24
work_mem = 12MB # pgtune wizard 2016-03-24
wal_buffers = 8MB # pgtune wizard 2016-03-24
checkpoint_segments = 16 # pgtune wizard 2016-03-24
shared_buffers = 480MB # pgtune wizard 2016-03-24
max_connections = 80 # pgtune wizard 2016-03-24
谢谢！
