Performance problem with gin index

[Bertrand Paquet <bertrand.paquet@xxxxxxxxxxx>]

Hi,

We have got big slow down on our production plateform (PG 9.4.4).

After analyzing wals with pg_xlogdump, we see lot of writing in Gin Indexes.

We suspect slow down are related to the write of pending update on the index.

So, is there any method to see

- what is the current config of gin_pending_list_limit on a given index ?

- the current size of pending list on a given index ?

Regards,

Bertrand
