I've a table with tsvector column named meta_vector. Over this column there
is a gin index. When I execute query like:
select id from theses where meta_vector @@@ to_tsquery('cs', 'foo | (!bar)')
I get an errror message: query requires full scan, which is not supported by
GIN indexes.
The weird thing is, that when I drop the index, or disable index scans, it
works. Why can't the planner just use full scans instead of index scans on
such the queries? Thanks for help.
