Subject: [GENERAL] R: Hot disable WAL archiving

Hi Albe and thank you, first of all.

Is there a way to disable Wal logging only for specific table, permanently?

Yes.

You can set it to NO LOGGING

Alter table table_name set unlogged;

https://www.postgresql.org/docs/9.5/static/sql-altertable.html

Thank you again!
Francesco

You can set 'archive_command=/bin/true' and reload, then no WAL archives will be written.

Make sure to perform a base backup as soon as your bulk load is finished.

Yours,
