Обсуждение: Tsearch2 can't be checked for equality?

Hi all,

I'm trying to compare between 2 tsvector fields and I'm encountering a problem, for example:

test.com=> SELECT 1 WHERE to_tsvector('default', 'bh da') = to_tsvector('default', 'bh da');
 ?column?
----------
(0 rows)


There is another way that I can check for equality of 2 tsvector fields?

Thanks a lot in advance,
  Ben-Nes Yonatan

What version ?
in CVS HEAD I have

postgres=# select to_tsvector('english', 'bh da') = to_tsvector('english', 'bh da');
  ?column?
----------
  t
(1 row)

I think, it should works in 8.2 also.

A look at the CVS log suggests it should work in 8.1.5 and later.

            regards, tom lane

Well I got version 8.1.4 here and no option for upgrade... never mind I'll solve my problem in a different way.

Thanks a lot,
