The following bug has been logged on the website: Bug reference: 13837 Logged by: Alain Laporte Email address: alain.laporte12345@gmail.com PostgreSQL version: 9.4.5 Operating system: Linux Description: Hi, I use PostgreSQL 9.4.5 and I have activated the parameter track_commit_timestamp to use BDR (0.9.3) and to be able to replicate two databases. A directory pg_committs was created (this directory is named pg_commit_ts in PostgreSQL 9.5 => http://www.postgresql.org/docs/9.5/static/storage-file-layout.html), but, his content is not periodically deleted (all files stays after 2 weeks of running). I'm not sure if it's a bug (in PostgreSQL or BDR) or if my configuration is wrong. So, see bellow my configuration: name | setting | ------------------------------------+--------------------------------------------------+ allow_system_table_mods | off | application_name | psql |
