Hi
This is to check regarding an issue we came across on postgreSQL community version 11 with minor patch 11.20 along with few other changes
change details mention on end part of this mail
The issue is notice after the minor patching from postgreSQL 11.16 to 11.20
The particular database runs on a dockerized platform
Issue :
One of the table query not woks when string values are filtered with = clause
where as the query works with like clause using '%' flag or using trim(column)
below are query examples describes the problem
not working
select * from atlas_order.gdp_ship_logistic_food cgslf where shipping_group_id = '2VxFRCOG9tc7SjQ2Ogg0bveve96';
working
select * from atlas_order.gdp_ship_logistic_food cgslf where shipping_group_id like '%2VxFRCOG9tc7SjQ2Ogg0bveve96%';
select * from atlas_order.gdp_ship_logistic_food cgslf where shipping_group_id like '2VxFR%COG9tc7SjQ2Ogg0bveve96';
select * from atlas_order.gdp_ship_logistic_food cgslf where trim(shipping_group_id) = '2VxFR%COG9tc7SjQ2Ogg0bveve96';
select * from atlas_order.gdp_ship_logistic_food cgslf where shipping_group_id like '2VxFR%COG9tc7SjQ2Ogg0bveve96';
select * from atlas_order.gdp_ship_logistic_food cgslf where trim(shipping_group_id) = '2VxFR%COG9tc7SjQ2Ogg0bveve96';
Later as per the feedback from dev we have dropped and recreated the constraints and rebuild the indexes of the affected tables
and the data is accessible after on
the similar pattern is noticed across other tables related to primary - foreign key relationships
Could you please provide a feedback whether similar issues are reported on 11.20 release
or what could be the reason for the error
