Error code

PostgreSQL 53100

POSTGRESQL53100
Database Error Code· An error code returned by a database server such as PostgreSQL or MySQL.

What it means

disk_full — the server ran out of disk space.

How to fix it

  1. Free disk space immediately by removing old WAL segments or vacuuming bloated tables.
  2. Expand the disk or move tablespace data to a larger volume.
  3. Set up a low-disk-space alert so the condition is caught before the partition fills.
