Date: Thu, 30 Nov 2023 10:54:36 +0000
Message-ID: <18218-8cbdd922e41ea291@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 18218
Logged by: Baurzhan Sakhariyev
Email address: baurzhansahariev@gmail.com
PostgreSQL version: 15.0
Operating system: MacOS
Description:
https://www.db-fiddle.com/f/cpNjWRLmQT6UFb2wEo2LoG/0
select 'TextToMatch' like any (array[E'Te\%tch', E'nomatch']); -- true,
correct
select 'TextToMatch' NOT like any (array[E'Te\%tch', E'nomatch']); -- true
but must be false because it's a negated version of the expression above
Please note, that versions without E'' work as expected.
select 'TextToMatch' like any (array['Te\%tch', 'nomatch']); -- false
select 'TextToMatch' NOT like any (array['Te\%tch', 'nomatch']); -- true
