GIN does have a "pending list" of insertions not yet pushed into the main
index structure, and search performance will suffer if that gets too
bloated.  I don't recall much about how to control that, but I think
vacuuming the table will serve to empty the pending list.  Also see

Correct, if I want use that index immediately with same performance I have to call

select pg_catalog.gin_clean_pending_list('idxphones');

Or wait next autovacuum.

thanks
