Dear community,

After upgrade of Posgres from version 13.5 to 16.2 we experience following error:

could not extend file "pg_tblspc/16401/PG_16_202307071/17820/3968302971" with FileFallocate(): No space left on device

We cannot easily replicate problem. It happens at randomly every 1-2 weeks of intensive query computation.

Was there some changes in space allocation from Posgres 13.5  to Posgres  16.2?

Database has  size 91TB and has 27TB more space available.
