Обсуждение: tsearch2 question

In my tsearch2.sql there are statements like :


--dict interface
CREATE FUNCTION lexize(oid, text) returns _textas '$libdir/tsearch2'language 'C'with (isstrict);


I don't think $libdir is the real value that we want. Do I need to set
some special parameters with ./configure (in the root level of the source
tree) to replace $libdir with the real library path?

Thanks

Yes it is.
        regards, tom lane

But then when I do a psql < tsearch2.sql, it complains:

bash-2.05a$ psql testdb < tsearch2.sql 
SET
BEGIN
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index 
'pg_ts_dict_pkey' for table 'pg_ts_dict'
CREATE TABLE
ERROR:  stat failed on file '$libdir/tsearch2': No such file or directory
ERROR:  current transaction is aborted, queries ignored until end of 
transaction block
ERROR:  current transaction is aborted, queries ignored until end of 
transaction block
...
(and the ERROR message repeats many times)

Where did I do wrong??

Thanks

Did you do "make install" after building tsearch2?

If you did, maybe it installed tsearch2.so in the wrong place?
("pg_config --pkglibdir" will tell you what the backend thinks
"$libdir" means.)
        regards, tom lane

When I run psql < tsearch2.sql, is psql going to substitute $libdir 
internally with what $libdir really is (in my case, it would be 
/usr/lib/pgsql)? 

Thanks

Not psql, the backend.  The point of this is that your CREATE FUNCTION
definition can be platform-independent ...
        regards, tom lane

When I ran psql testdb < untsearch2.sql

I got the following error message:

psql:untsearch2.sql:15: ERROR:  RemoveAggregate: aggregate stat(tsvector) 
does not exist

I didn't really do anything before this. Only dropped the trigger and gist 
index I created (in order to use tsearch2), and alter table testtb drop 
column idxtest tsvector.

Where did I do wrong?

Thanks
