Found this a couple of weeks back and just re-tested against head:
CREATE TEXT SEARCH DICTIONARY with an empty thesaurus file will crasch
the backend.
To reproduce:
$ echo "" > $(pg_config --sharedir)/tsearch_data/thesaurus_empty.ths
Then use this thesaurus to create a text search dictionary:
CREATE TEXT SEARCH DICTIONARY thesaurus_astro (
TEMPLATE = thesaurus,
DictFile = thesaurus_empty,
Dictionary = english_stem
);
It doesn't matter if the file is compleatly empty or just have comments.
The result is the same.
Add a word:
$ echo "foo: bar" >> $(pg_config
--sharedir)/tsearch_data/thesaurus_empty.ths
Creating the dictionary will now work.
Sorry I have no patch to attach.
Regards,
roppert
PS. I happend to send this mail from a wrong, non-subscribed, address
