PostgreSQL DBMS_JOB compatibility extension

pg_dbms_job is a PostgreSQL extension to create, manage and use Oracle-style DBMS_JOB scheduled job. The use and behavior is just like with the DBMS_JOB Oracle package.

pg_dbms_job v1.1.0 has been released, this is a maintenance release to fix some possible wrong behaviors, give control over other ones and improve the documentation.

• Add configuration directive job_queue_processes to control the limit of jobs that can be run at the same time.
• Fix insertion failure in job history table when PQSTATUS returned contains single quote.
• Fix possible case where asynchronous jobs can be executed twice if they are not removed fast enough from the queue.
• Fix regression test to use latest SQL version of the extension.
• Add limitations on pg_dbms_job use and especially about the NOTIFY queue size limits. Thanks to Julien Rouhaud for the report.
• Add missing information on how to stop or reload configuration of the scheduler.
• Add information that unlike with cron-like scheduler, when the scheduler starts it executes all active jobs with a next date in the past.
• Add information that jobs are executed with the role that has submitted the job and with the search path was used at job creation time.

To upgrade installed pg_dbms_job version 1.0.1 execute:

ALTER EXTENSION pg_dbms_job UPDATE;

after installing the new version using: make && sudo make install
