postgresql-9.2

I want to import a CSV file into version 9.2 but the CSV file has double-quote double-quote in the final column position to represent a NULL value: "2","1001","9","2","0","0","130","","2012-10-22 09:33:07.073000000","" which is mapped to a column of type Timestamp. postgreSQL doesn't like the "". I've tried to set the NULL option but maybe I'm not doing it correctly? I've tried NULL as '"" and NULL '' and NULL as '' and NULL "" but without success; here's my command: COPY SCH.DEPTS FROM 'H:/backups/DEPTS.csv' WITH ( FORMAT CSV, DELIMITER ',' , NULL '', HEADER TRUE, QUOTE '"' ) but it fails

I'm trying to work with current_setting() . I came up with this: CREATE OR REPLACE FUNCTION process_audit() RETURNS TRIGGER AS $audit$ DECLARE user_id integer; BEGIN BEGIN user_id := current_setting('hws.current_user_id'); EXCEPTION WHEN OTHERS THEN user_id := NULL; END; ... RETURN NULL; END; $audit$ LANGUAGE plpgsql; The setting is set via: SELECT set_config('hws.current_user_id', '5', true); -- true = local setting -> only visible in current transaction The problem is, that current_setting() throws an exception if the value is not valid. I don't want to use EXCEPTION because I read that

I need to restrict the number of digits in the 'integer' type fields to 6 or 7 in postgres. Basically it should accept 123456 or 1234567 but it should not accept 12345 or 12345678. How can I achieve this?? Have a check constraint with check (value>99999 and value<=9999999) You can use floor(log(i)+1 to get the number of digits in a number (that's base10 log). DB> CREATE TEMP TABLE t ( i integer CONSTRAINT i_has_6_or_7_digits CHECK (floor(log(abs(i))+1) BETWEEN 6 AND 7) ); CREATE TABLE Time: 5,676 ms DB> INSERT INTO t VALUES (123456), (1234567); INSERT 0 2 Time: 0,471 ms DB> INSERT INTO t

I am writing a script to alter all functions of postgres(changing owner of each function). I am able to list down all the function names using postgres query but not able to list parameters for each of those functions. My problem will be resolved if I get solution for any of the below mentioned problems: Is there any way to list down parameters' data type in each of the function. Do we have any approach to alter functions where instead of passing parameter type can I send some wild card. For Example can I write ALTER FUNCTION schemaname.func(text) OWNER TO 'newowner' as : ALTER FUNCTION

I am having a problem changing the data directory on postgresql 9.2 on windows7: i`m trying to change my data directory: how can i change data directory on postgreSQL with pgAdmin? This not possible from within pgAdmin (or any other SQL client because you need to stop the Postgres server in order to move the data directory) To move the directory, use these steps: Stop Postgres (you can use the control panel to find the correct service name) net stop <name_of_the_service> Make sure Postgres is not running (e.g. using ProcessMonitor) Remove the Windows service using pg_ctl unregister -N <name_of
