Re: SV: Log files polluted with permission denied error messages after every 10 seconds

[Andrus]

Today log file contains

2021-03-10 11:01:58 EET     checkpointer LOG:  could not rename file 
"pg_wal/000000010000000A0000003B": Permission denied

messages. Resource Manager shows that 000000010000000A0000003B is is 
locked by process 30376


According to pg_stat_activity this is regular postgres process which is 
in idle state and waiting for ClientRead event. It has executed last 
query  an hour ago.

It looks like wal files are not released after usage.
