Обсуждение: Missing mapping in 8.3/tsearch2.sql

All,

The Tsearch2.sql compatibility fuctions in 
/contrib/tsearch2/tsearch2.sql don't include an important compatibility 
object.  For 8.2 Tsearch2 usage, a lot of queries were written calling 
the "default" config, like:

to_tsvector('default',somedata)

In 8.3 this fails with a "No such config 'default'" error, even after 
loading the compatibility SQL.  We need to add this to the compatibility 
SQL generation code:

CREATE TEXT SEARCH CONFIGURATION public.default ( COPY = 
$default_text_search_config );

Yes?

No, we should not.  It's up to the user to create a "default" config
that matches whatever they were using before.

Now, if you are volunteering to create a translation facility for the
whole contents of the old configuration tables, step right up and have
at it.  But we should *not* insert a bogus substitute configuration.

Oh, good point.  I was assuming that "Default" would match the user's 
default, but of course it might not.

Hmmm, this is a common enough case that it ought to be documented 
somewhere though.    How about if I add an example to F.31.2. Converting 
a pre-8.3 Installation ?

I think it already points out the need to manually convert your
configuration, but feel free to fill in some details there.  I would
have if I knew enough to explain it ...
