postgresql-9.1

Is it really impossible to use default schema for Spring Security with PostgreSQL, because the part "varchar_ignorecase" does not exist can't be replaced? I'm just testing the default settings: auth.jdbcAuthentication() .dataSource(dataSource) .withDefaultSchema(); And below is the error: Caused by: org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public javax.servlet.Filter org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration.springSecurityFilterChain() throws java.lang.Exception] threw exception; nested exception is org

I have a PostgreSQL 9.1 database with a table containing a timestamp and a measuring value '2012-10-25 01:00' 2 '2012-10-25 02:00' 5 '2012-10-25 03:00' 12 '2012-10-25 04:00' 7 '2012-10-25 05:00' 1 ... ... I need to average the value over a range of 8 hours, every hour. In other words, I need the average of 1h-8h, 2h-9h, 3h-10h etc. I have no idea how to proceed for such a query.

I would like to extract the week number as: 2015-52 from a date formatted as: 2015-12-27 How can I perform this in postgres? my weeks are calculated from monday to sunday. To get the year and the week in a single character value, use to_char() select to_char(current_date, 'IYYY-IW'); IW returns the year and the week number as defined in the ISO standard and IYYY returns the corresponding year (which might be the previous year). If you need the year and the week number as numbers, use extract select extract('isoyear' from current_date) as year, extract('week' from current_date) as week; You can

If I have the following table: Table "users" Column | Type | Modifiers ---------------+------------------+----------- id | integer | not null default nextval('users_id_seq'::regclass) monthly_usage | real[] | Where monthly_usage is an array of 12 numbers, i.e. {1.2, 1.3, 6.2, 0.9,...} How can I select the sum of that column? Something along the lines of: SELECT id, sum(monthly_usage) as total_usage from users; Which obviously doesn't work. Dmitry Seleznev SELECT id, (SELECT SUM(s) FROM UNNEST(monthly_usage) s) as total_usage from users; This generalization and reformatting Dmitry 's answer

I have just installed the postgreSQL on windows 7. I am trying to integrate postgreSQL with WAMP server.
