PG::DiskFull Error

Hi,

this error was raised in my application where the standard postgres database is at 4.95% used out of 16.0 GiB

PG::DiskFull: ERROR: could not resize shared memory segment "/PostgreSQL.1934435548" to 2097152 bytes: No space left on device CONTEXT: parallel worker

How ofter does this error happen?

The error happened only once in a web instance 13.01.2021 15:48:21 CEST

But the type of error does leave mit with serious doubt on the reliability of the postgresql service-level…
