Subject: BUG #18159: Database Integrity Concerns: Missing FK Constraint
Date: Mon, 16 Oct 2023 20:26:26 +0000
Message-ID: <18159-d47c6a6b62e40f00@postgresql.org> (raw)

The following bug has been logged on the website:

Bug reference:      18159
Logged by:          Root Cause
Email address:      rootcause000@gmail.com
PostgreSQL version: Unsupported/Unknown
Operating system:   Windows
Description:        

Version - PostgreSQL 10.21, compiled by Visual C++ build 1800, 64-bit

We are currently experiencing issues in the database where foreign key (FK)
constraints are missing, leading to orphaned rows. Upon investigation, we
suspect that we are currently running a vacuum on tables according to a
schedule, and also as a standalone process when the product is not
running.

Is there a possibility that during the vacuum process, FK constraints might
be dropped and recreated for restructuring? If so, are there any chances
that they will not be recreated?
