File _service:tar_scm:CVE-2022-44566.patch of Package rubygem-activerecord

Subject: [PATCH] Added integer width check to PostgreSQL::Quoting

Given a value outside the range for a 64bit signed integer type
PostgreSQL will treat the column type as numeric.
Comparing integer values against numeric values can result
in a slow sequential scan.

This behavior is configurable via
ActiveRecord.raise_int_wider_than_64bit which defaults to true.
