Subject: Query about pg_wal directory filled up
Date: Tue, 17 Dec 2024 19:11:55 +0530
Message-ID: <CAJWX+EMoXWiSu3Jev9p71VmZ+jGBKuYg3J2r5ZDxsuuKpPbHcw@mail.gmail.com> (raw)

Hi Team,

One of our clients recently migrated from Oracle to PostgreSQL and is
conducting multiple scenarios to understand PostgreSQL behavior.

One of their main concerns is whether the database will allow `INSERT`
queries when the `pg_wal` directory becomes full.

As I understand, once the `pg_wal` directory is completely filled, the
database will allow only read queries and will not permit any write
operations.

Kindly advise


Thanks
RK
