The query you show is not executed merely due to the passage of time.
Something is executing that query. It is probably a monitoring tool.

Since procpid was removed back in version 9.2, the monitoring tools seems
massively out of date. It is possible this tool has buggy code to detect
the version, and concludes that v11 is prior to 9.2. But that seems
unlikely to be broken by v11 but not by v10. Do you have the same problem
in v10?

Figure out what your monitoring tool is and report the bug to its
maintainer.
