This has happened to us where we have dead or unmanaged consumer. Turns out londiste is keeping the event even if the consumer is unreachable. This is to ensure that the consumer gets what it should.

Re: [GENERAL] Londiste 3 pgq events_1_1 table huge
Queue - Event are stored in queue tables i.e queues. Several producers can write into same queue and several consumers can read from the queue. Events are kept in queue until all the consumers have seen them. Maybe you have some inactive consumers holding a event tables. qadmin -h -p 5432 -U postgres -d -Q Use 'show help;' to see available commands. copy output of show consumer command show consumer; Rene From: pgsql-general-ow...@postgresql.org on behalf of Leonardo M.

Hi, Check for long running Idle in transaction sessions. Idle in transaction sessions may holding events table from cleaning itself up. If there is more then days long running idle in transaction sessions, kill them, event table should be cleaned automatically after that.
