Обсуждение: Hot disable WAL archiving

Hello,

is there a way in Postgresql-9.5 to disable temporarily WAL archiving to speed up pg_bulkload with restarting database
engine?

Thank you,
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.

Hi Albe and thank you, first of all.

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

Thank you again!
Francesco
