Hi, Baurzhan! I've checked the requests and here's what I think about it. There is no mistake here. Here's how I tested 1. select 'TextToMatch' like E'Te\%tch' returns true. 2. select 'TextToMatch' like E'nomatch' returns false. 3. select 'TextToMatch' not like E'Te\%tch' returns false. 4. select 'TextToMatch' not like E'nomatch' returns true. LIKE ANY 1, 2 equals true. LIKE NOT ANY 3, 4 equals true. Maybe you need to use NOT ALL? >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
