Thanks for the response!
* We are on version 9.5.6
* Less than 10% of the table was updated today (between the time of the last
reindex to when performance deteriorated)
* autovacuum is on. I don't see an autoanalyze property in config but these
are the settings for analyze
/autovacuum_analyze_threshold = 3000 # min number of row updates before
analyze
#autovacuum_vacuum_scale_factor = 0.2 # fraction of table size before
vacuum
#autovacuum_analyze_scale_factor = 0.1 # fraction of table size before
analyze
#autovacuum_freeze_max_age = 200000000 # maximum XID age before forced
vacuum
# (change requires restart)/
* And this #gin_pending_list_limit = 4MB
* gin_clean_pending_list() is not available.
Will play with gin_pending_list_limit and see what that does.
Thanks!
RV
