How to prevent master server crash if hot standby stops - Mailing list pgsql-general

Hi!

Streaming asynchronous binary replication is used with hot standby slave.

If slave stops responing, master server will create files in pg_wal directory.
If disk becomes full, master server crashes also.

How to avoid this ?

If disk is nearly full, master should stop additional files creation (and maybe stop or disable replication slot).
Postgres 12 in Debian 10 is used.

Andrus.
