PostgreSQL sometimes initializes with a non-invariant locale (e.g. en_US.UTF-8, ru_RU.UTF-8).
As a result, date strings are parsed and formatted differently than in .NET using InvariantCulture, causing inconsistent results when inserting or reading dates.
Example
'01.02.2024'::timestamp → interpreted as Feb 1 or Jan 2 depending on locale.
Expected
Date behavior should be culture-invariant and consistent across environments.
