Interesting...that seems to be the case. For example, this will fail:
explain analyze
select *
from test.features
where to_tsquery('') @@ features.vector
ERROR: Gin doesn't support full scan due to it's awful inefficiency
Interestingly this works:
explain analyze
select *
from test.features
where NULL @@ features.vector
Here is a slightly bigger test case:
--drop schema test cascade;
create schema test;
CREATE TABLE test.maps
(
id serial,
query tsquery
);
CREATE TABLE test.features
(
id serial,
vector tsvector
);
CREATE INDEX features_vector ON test.features USING gin (vector);
INSERT INTO test.maps (query)
VALUES (to_tsquery(''));
INSERT INTO test.features (vector)
VALUES (to_tsvector('test'));
analyze test.maps;
analyze test.features;
--
Now try this, which won't work (ERROR: Gin doesn't support full scan
due to it's awful inefficiency):
set enable_seqscan to off;
explain
select *
from test.maps, test.features
where features.vector @@ maps.query
Nested Loop (cost=1.00..10004.04 rows=1 width=36)
-> Seq Scan on maps (cost=1.00..10001.01 rows=1 width=12)
-> Index Scan using features_vector on features (cost=0.00..3.01
rows=1 width=24)
Index Cond: (features.vector @@ "outer".query)
However, this works:
set enable_seqscan to on;
set enable_indexscan to off;
set enable_bitmapscan to off;
explain analyze
select *
from test.maps, test.features
where features.vector @@ maps.query
Nested Loop (cost=2.00..20002.03 rows=1 width=36) (actual
time=0.055..0.055 rows=0 loops=1)
Join Filter: ("inner".vector @@ "outer".query)
-> Seq Scan on maps (cost=1.00..10001.01 rows=1
width=12) (actual time=0.011..0.014 rows=1 loops=1)
-> Seq Scan on features (cost=1.00..10001.01 rows=1
width=24) (actual time=0.006..0.010 rows=1 loops=1)
Total runtime: 0.129 ms
You see the same things if you put a NULL in the query column (unlike
above). If instead, you do this in the script above:
INSERT INTO test.maps (query)
VALUES (to_tsquery('test'));
Then it always works.
Seems like the moral of the story, tsquery values of '' or NULL don't
work.
That is surprising to me - maybe the documentation should point out this
issue?
Thanks,
Charlie

[GENERAL] what fired a trigger
Hi, The most general problem that may be a design problem (and I'm not asking to do my homework even if well, you may still help ) is I've a "temporary relation" and a permanent relation. A typical situation is the one of session in a web app and temporary basket. Once the user log in, the temporary basket becomes "permanent". But I'd like automatic garbage collection for all tables simply related to sessions. When a session get deleted all row that are *just* related to the session, but not to the user, should be deleted. Anyway I still need normal "User related" delete. The partial solution I found need to distinguish what fired a trigger another trigger or a "plain delete" and pass it on to the other triggers. I've something similar: create table T_Session ( idSession char(32) not null default md5(now() || random()) ) alter table T_Session add constraint PK_Session primary key (idSession) ; create table T_User ( idUser integer , idSession char(32) --should stay here or in a t_Session_User(idSession,idUser)? ); alter table T_User add constraint PK_User primary key (idUser) ; create table T_Preferences ( idPreferences integer , idSession char(32) ); alter table t_Preferences add constraint PK_Preferences primary key (idPreferences) ; alter table t_Preferences add constraint FK_Preferences_Session foreign key (idSession) references t_Session (idSession) on delete cascade ; alter table t_Preferences add constraint FK_Preferences_User foreign key (idUser) references t_User (idUser) on delete cascade ; create table t_Preferences_Stuff ( idStuff integer , idPreferences integer ); alter table T_Preferences_Stuff add constraint PK_Preferences_Stuff primary key (idStuff) ; alter table T_Preferences_Stuff add constraint FK_Preferences_Stuff foreign key (idPreferences) references T_Preferences (idPreferences) on delete cascade ; create or replace function TG_SessionDelete( ) returns trigger as ' begin if OLD.idUser is not null then return null; else return OLD; end if; end; ' language plpgsql; create trigger TG_SessionDelete before delete on T_Preferences for each row execute procedure TG_SessionDelete(); Now if I delete a session with something like delete from t_Session where idSession='..'; all the row in the linked tables where the idUser is null should be deleted. If the row has a not null idUser it shouldn't be deleted. And this works. But what if I'd like to obtain those behaviour too: 1) delete from T_Preferences where idSession=''; should delete all row in linked tables, no matter if idUser is null or not I'm still thinking if this is actually what I want since if there is a link to idUser I may use idUser to delete rows. So I could split deletion related to session operations and deletion related to user operations. 2) delete from T_User where idUser=10; delete from T_Preferences where idUser=37; should delete all row in linked tables. the above trigger doesn't work. I've tried to understand if there is a way to exploit TG_ARGV[] & Co. but I didn't understand even how to use it.

If you just need a simple solution, look up domains: http://www.postgresql.org/docs/8.1/static/sql-createdomain.html specifically: create domain varchar2 as varchar; Note that you won't have a precision argument on the varchar2, but you can put one on the varchar you use during domain creation: This works: create domain varchar2 as varchar(200); create table test (info varchar); This doesn't: create domain varchar2 as varchar; create table test (info varchar(200)); But once the tables are created, insert statements and such should work normally. ---(end of broadcast)--- TIP 4: Have you searched our list archives? http://archives.postgresql.org
