Summary0012019: Postgres error: tuple concurrently updated, caused by call using sessionConfig value
DescriptionWhen a user calls many webservices in a short time then he/she encounters a various moments a 'tuple concurently updated' exception. See below. This happens when the sessionConfig is executed which for postgresql is this:
bbdd.sessionConfig=select update_dateFormat('DD-MM-YYYY')

The update_dateFormat SP replaces the dateFormat SP with a new implementation. It does this by creating/replacing the existing function. This create/replace is done at every connection creation.

Proposed solution:
- for postgres hardcode a call "select update_dateFormat('DD-MM-YYYY')" when the application starts (in a context listener or something)
- clear the sessionConfig value in openbravo.properties (and the template) for postgres
- create a new update_dateformat SP and clear the old one (let it not change the dateformat definition). This means that existing OB instances will call a harmless SP
- when the application starts perform once: select update_dateFormat('DD-MM-YYYY', where DD-MM-YYYY is read from the darformat.sql present in Openbravo.properties

A different and easier solution is to change the update_dateformat database function to update when the dateformat has changed, so change the definition to this:

DECLARE
BEGIN
  IF (dateformat() <> format) THEN
  EXECUTE 'CREATE OR REPLACE FUNCTION dateFormat() RETURNS VARCHAR AS '' DECLARE BEGIN RETURN ''''' || format || '''''; EXCEPTION WHEN OTHERS THEN RETURN NULL; END; '' LANGUAGE ''plpgsql'' IMMUTABLE; ';
  RETURN 'dateFormat modified';
  END IF;
  RETURN 'dateFormat not modified';
END;

tested with concurrent read queries to Country entity. without patch error shows up immediately. With patch survives 50 requests at concurrency 10 without problems.
