it should be "audit_log" ('xtable','internal'), it works.

I got that wrong, it actually installs tsearch2.sql into $libdir/../share/contrib/ without specifically setting a different location for shared files. However, I also note that the functions are installed into public schema. That looked fine when I first checked that it wasn't polluting namespaces in the search path. Unfortunately, the database I'm looking at at the moment doesn't have public in the user's search paths. Therefore, I'm going to have to bring tsearch2 into my own release procedures, something not made easy by it only being compilable within the contrib directory of the main source tree. -- Nigel J.

[GENERAL] Querying $libdir
The subject says it really. Is there a way to query the value of $libdir, and I don't mean the dynamic_library_path GUC? I ask because, I have scripts to create databases and I've come to make adjustments to load tsearch2. Now contrib/tsearch2 installs itself into $libdir with tsearch2.sql installed as $libdir/contrib/tsearch2.sql. So my scripts either need to know via hardcoding where tsearch2.sql is installed, try to work it out from file system searching, ask the user running the scripts or obtain it from the horses mouth. Hardcoding where I think it is installed is fine until the build happens on a system I don't control. Same thing for a list of hardcoded likely locations. File system searching again uses information about where I think things are installed or tries to determine it by finding out where applications like psql are located (assuming the picked up psql is part of the same installation as the backend it is talking to) and doing some jiggery pokery from there, again making some installation location assumptions to find a suitably named file. Asking the user is fine, would work and is a reasonably quick solution. It just spoils the look of things when scripts run by other scripts start pestering the user for info about the system things. Or, I could just ask the horses mouth by issuing a query in the backend via psql. Guess which I think I want to use. The question being is this even possible in a stock 7.3 server? I know it's not the right list but seeing as I'm emailing. tsearch2 doesn't even compile outside of contrib/ I presume that is necessary? Is there any particular reason why the stop word files are installed with no permissions for 'world'? It kinda screws up installing as one user and running as another. -- Nigel J.

OK, so all you have shown me is the output from the first loop of pg_autovacuum. The PointUsage table was added, the stats system had reported 0 inserts update or deletes when the table was added, and when it was checked 0.2 seconds later, it still had reported no deletes, so at this point it is correct in not doing a vacuum. What I really need is the logoutput from before, during and just after you insert / update / delete from the PointUsage table. Also, setting your threshold values lower helps if you just want to see pg_autovacuum actually fire off a vacuum. So you probabaly want to do somethign like this: pg_autovacuum -d2 -s1 -S0 -v10 -V0 -a10 -A0 -L pg_autovacuum.out this will set debug=2, sleep only 1 sec after each look, and perform vacuums and analyzes after only 10 insert/update/delets and log it all to pg_autovacuum.out Run your update script Kill pg_autovacuum bzip the logfile and send it to the mailing list (or just to me if you prefer).

But not without root access or logging in as postgres :) I would suggest that if you can't get your ISP to install the startup script where is should be (/etc/init.d/ and the appropiate symbolic link) then don't use the postgres user for your database. Presumably as admin you can administer users. So create a new user, say postgres2. Initialise a data directory: $ initdb -D ~postgres2/data as that new user. Then when you need to you can at least start the db manually by logging in as postgres2, which you are able to do since you have control over that user. -- Nigel J.

[GENERAL] Problems with GRANTING SELECT to a table
Title: Problems with GRANTING SELECT to a table
Hi,
I have a problem with permissions for SELECT.
Here is what I did:
test=> GRANT SELECT ON "poi"."fondsstamm" TO "flex";
GRANT
test=> \dp fondsstamm;
Access privileges for database "test"
Schema | Table | Access privileges
++---
poi | fondsstamm | {=arwdRxt,poi=arwdRxt,flex=r}
(1 row)
Now when I try to select from the table poi.fondsstamm
I become always the error: Permission denied,

Yes. Do a CVS checkout and check History and TODO files. There are fairly well maintained. Also check pending patches. http://developers.postgresql.org is the palce to start. 7.4 Documentation is another place you could check for new features.. I think it could have been better organised. A huge bugzilla like KDE uses could be a great thing. But for sure, there is nothing missing. You just need to get tuned to the way postgresql gets developed.

Name calling ("control freak") is childish.
If you are not a lawyer and you want to bet that dynamic linking to a
GPL'ed library doesn't invoke the GPL then I think you're taking a
gamble. Clearly you think you know more about the law than the FSF
General Counsel Eben Moglen (professor of law at Columbia).
Combined works dynamically linked to GPL libraries involve untested
legal issues. The legal issues are complex, and when law and
technology collide it can be hard to predict the outcome. RMS
believes the GPL is enforcable in this case, but until someone is
willing to be sued by the FSF over this no one will know for sure.
(None of the GPL violators the FSF has pursued have been willing to
risk a trial so far.)

All of this appears to be in order. I think we need some more
information. First, what options are you setting? What is the exact
command you are using to launch pg_autovaccum. Some output from
pg_autovacuum with debug level set to 2 would be helpful. Also, what OS
/ compiler are you using?
BTW: are you sure that you have performed enough inserts / updates /
deletes to exceed the thresholds? (debug level 2 will tell you what the
thresholds are.

> So? Is there a way to add the sequence to an existing table?
Sure. You have to break the SERIAL down to its component parts though.
Something like
CREATE SEQUENCE seq;
ALTER TABLE tab ADD COLUMN ser INTEGER;
UPDATE tab SET ser = nextval('seq');-- this will take awhile
ALTER TABLE tab ALTER COLUMN ser SET DEFAULT nextval('seq');
ALTER TABLE tab ALTER COLUMN ser SET NOT NULL;
-- possibly also add a UNIQUE constraint
We haven't yet got round to supporting ADD COLUMN ... DEFAULT because
according to the SQL spec that implies doing the UPDATE to fill the
column values immediately, and that's just a chunk of code no one's
written yet.

Yes, you have to list in the COPY command just the columns that are
actually being supplied in the input data. Columns not mentioned (like
the serial column) get filled from their defaults. I think this is
new in 7.3 ... it's pretty recent anyway.

A trigger is the right way. Rules rewrite a statement whereas triggers are at row level. so in plpgsql: create or replace function trig_param_ins_upd() returns trigger as ' begin new.ts = current_timestamp; return new; end;' language 'plpgsql'; create trigger trig_param_ins_upd before insert or update on param for each row execute procedure trig_param_ins_upd(); now whenever a new row is insert or a row is updated the trigger will ensure that ts always contains the current timestamp.

[GENERAL] adding SERIAL to a table
Hello
Now perhaps this is a bit dumb,
but...
I just populated a new table via \copy.
After that, I realize that perhaps is a good thing to have a row identifier in
it, so I try
clapidus=> alter table tickets add
column rid serial;NOTICE: ALTER TABLE will create implicit sequence
"tickets_rid_seq" for SERIAL column "tickets.rid"ERROR: adding columns
with defaults is not implemented
So my next guess is to define a test
table from scratch, this time with the serial field in place. Next I try
the \copy:
clapidus=> create table test(rid serial,
col_a text);NOTICE: CREATE TABLE will create implicit sequence
"test_rid_seq" for SERIAL column "test.rid"CREATE TABLEclapidus=> \d
test
Table "test" Attribute | Type
|
Modifier---+-+--- rid
| integer | not null default
nextval('public.test_rid_seq'::text) col_a |
text |
clapidus=> \copy test from
stdin23 a
record45 another record\.clapidus=>
select * from test ; rid |
col_a-+ 23 | a record 45 | another
record(2 rows)
Now the first character from stdin is a
tab, in a try to let the sequence come into action:
clapidus=> \copy test from
stdin still another
record\.ERROR: invalid input syntax for integer: ""PQendcopy:
resetting connection
Grrr. Third attempt:
clapidus=> \copy test from stdin with
null as 'NULL'NULL still another one\.ERROR:
null value for attribute "rid" violates NOT NULL constraintPQendcopy:
resetting connection
So? Is there a way to add the sequence to
an existing table?
Or, alternatively, is there a way to issue
a \copy command while letting the sequence fill in the serial
field?
thanks in advance
