I have a simple table, and a gin index,
create table mytable(hash char(40), title varchar(500));
create index name_fts on mytable using gin(to_tsvector('english', 'title'));
^^^^^
create unique index md5_uniq_idx on mytable(hash);
When I execute a query with tsquery, the GIN index was not in use:
test=# explain analyze select * from mytable where
to_tsvector('english', title) @@ 'abc | def'::tsquery limit 10;

Any ideas?
