Hi,
I have very slow performance for a TSearch2 table. I have pasted the

purpose. Is there any way to speed this up?
# explain analyze select * FROM fulltext_article, to_tsquery
('simple','dog') AS q WHERE idxfti @@ q
I'm new in PostGreSQL and I need some help.
I have a table with ~2 million records. Queries in this table are too slow and
some are not completed.I think it must be a simple question to solve but, I'm
trying without success. I'm worried because next week I will need to work with
tables with
