postgresql-8.4

I am trying to configure ssl certificate for postgreSQL server. I have created a certificate file (server.crt) and key (server.key) in data directory and update the parameter SSL to "on" to enable secure connection. I just want only the server to be authenticated with server certificates on the client side and dont require the authenticity of client at server side. I am using psql as a client to connect and execute the commands. I am using PostgreSQL 8.4 and linux. I tried with the below command to connect to server with ssl enabled psql "postgresql://localhost:2345/postgres?sslmode=require"

I have a PostgreSQL database with a table holding dates. Now I need to find all rows within the date range 15/02 until 21/06 (day/month) across all years. Example result: 1840-02-28 1990-06-21 1991-02-15 1991-04-25 1992-05-30 1995-03-04 1995-04-10 2001-02-03 2010-04-06 Assuming (with a leap of faith) that you want dates between certain days of the year regardless of the year (like if you're sending out a batch of birthday cards or something), you can set up a test with this: CREATE TABLE d (dt date); COPY d FROM STDIN; 1840-02-28 1990-06-21 1991-02-15 1991-04-25 1992-05-30 1995-03-04 1995-04

(PostgreSQL 8.4) Continuing with my previous example , I wish to further my understanding of gaps-and-islands processing with Window-functions. Consider the following table and data: CREATE TABLE T1 ( id SERIAL PRIMARY KEY, val INT, -- some device status INT -- 0=OFF, 1=ON ); INSERT INTO T1 (val, status) VALUES (10, 0); INSERT INTO T1 (val, status) VALUES (11, 0); INSERT INTO T1 (val, status) VALUES (11, 1); INSERT INTO T1 (val, status) VALUES (10, 1); INSERT INTO T1 (val, status) VALUES (11, 0); INSERT INTO T1 (val, status) VALUES (10, 0); As previously explained, the devices turn ON and OFF

Following on from this earlier question I'm on PostgreSQL 8.4 and am having trouble with updatable views. I have a view: CREATE VIEW filedata_view AS SELECT num, id, ST_TRANSFORM(the_geom,900913) AS the_geom FROM filedata And want to update it from my application throw Geoserver. But get a error: <ServiceExceptionReport version="1.2.0" xmlns="http://www.opengis.net/ogc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/ogc http://schemas.opengis.net/wfs/1.0.0/OGC-exception.xsd"> <ServiceException> {http://www.opengeospatial.net/cite}filedata_view

I've just inherited an old PostgreSQL installation and need to do some diagnostics to find out why this database is running slow. On MS SQL you would use a tool such as Profiler to see what queries are running and then see how their execution plan looks like. What tools, if any, exist for PostgreSQL that I can do this with? I would appreciate any help since I´m quite new with Postgres. Use pg_stat_statements extension to get long running queries. then use select* from pg_stat_statements order by total_time/calls desc limit 10 to get ten longest. then use explain to see the plan...

I'm creating a select statement that combines two tables, zone and output , based on a referenced device table and on a mapping of zone_number to output_type_id . The mapping of zone_number to output_type_id doesn't appear anywhere in the database, and I would like to create it "on-the-fly" within the select statement. Below is my schema: CREATE TABLE output_type ( id INTEGER NOT NULL, name TEXT, PRIMARY KEY (id) ); CREATE TABLE device ( id INTEGER NOT NULL, name TEXT, PRIMARY KEY (id) ); CREATE TABLE zone ( id SERIAL NOT NULL, device_id INTEGER NOT NULL REFERENCES device(id), zone_number
