Hi All,

Is anyone had face swap/memory or resource usage issue due to postgres
exporter.

We have observed one default select query part of exporter metrics which is
collecting some info from pg_stat_statment and calculating
percentile.(looks like heavy query). Suspecting  our prod environment was
down due to that statement which caused heavy swap.noticed that this
statement creating temp files (was   written in log file before it was
down).

Pls advice if any one come across this issue and share if any fix is
applied on this.

Postgres Version 16
Exporter Version 0.17.0
OS : Linux

Regards,
SK
