Re: Connection Broken with Custom Dicts for TSearch2

Sorry, but I thought it that was the most appropriate list for the issue.

I was following these instructions:
http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/custom-dict.html

And what happens is that the function works just once. Perhaps a malloc/free
issue?

$ psql fuzzy

fuzzy=# select to_tsvector('the quick brown fox jumped over the lazy dog
100');
to_tsvector
--------------------------------------------------------------------
'dog':9 'fox':4 'jump':5 'lazi':8 'brown':3 'quick':2 'hundred':10
(1 registro)

fuzzy=# select to_tsvector('the quick brown fox jumped over the lazy dog
100');
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

Rodrigo,

you gave us too little information. Did you use your own dictionary ?
What's your configuration, version, etc.

Oleg,

Actually I got PG 8.1.4 compiled from source on a Debian GNU/Linux
2.6.16-k7-2.
My locale is pt_BR, but I configured TSearch2 to use rules from the
'simple'.
Then I just followed the instructions from the link. The fact is that it
only works at the first time.

Rodrigo, it's not enough. If you built your dictionary, please, post it,
as well as tsearch2 configuration.

Aha,

I got the same problem on 8.2dev.

Sorry, it isn't mentioned on page, but this example of code working only with
before 8.1 versions. In 8.1 interface to dictionary was changed.

More precisely, in 8.1, lexize function (in num2english dlexize_num2english())
should return pointer to TSLexeme array instead of char**.

Since we are on the topic, is there a timeline/plans for openfts being
brought into core? If not, I'll continue my work on bringing it into
Gentoo Portage.

OpenFTS never, but tsearch2 is possible. But it requires enough work to do, so I
have doubt that it will be done in 8.2...

How about those "pg_ts*" tables, which are specific for a database? Will
they serve to the whole cluster?

No, it plans per database only.

If you need in all database, you can install tsearch2 into template1, so all
newly created database will have the same tsearch2 configuration.
