The following bug has been logged on the website:
Bug reference: 17676
Logged by: Rob Johnson
Email address: robj(at)hightouchinc(dot)com
PostgreSQL version: 14.5
Operating system: Ubuntu
Description:
No tables are needed. Just ran this, comparing strings with lower-case 'x'
and period '.' characters. The first two columns are false as expected, the
last column is true, which appears to be wrong.
=> select '.' > 'x' as first, '.x' > 'x.' as second, '.xx' > 'x..' as third;
first | second | third

My Postgres version:
=> select version();

(1 row)
I am located in the United States and haven't done anything to change
character sets, collations, or anything like that. The \l+ psql command
shows this for my database, which is called nigeldb:
=> \l+ nigeldb
