Please enter a FULL description of your problem:
------------------------------------------------
I am working on the creation of a CD database which contains a table
interpret. I made the following queries:

disky=> select * from interpret where lower(name) like 'the whatkee%';
intid|name|schreibw
-----+----+--------
(0 rows)

disky=> select * from interpret where lower(name) like 'the whatkeez%';
intid|name |schreibw
-----+--------------------------------------------------+--------
49|The Whatkeez | 0
(1 row)

disky=> select * from interpret where lower(name) like 'the whatke%';
intid|name |schreibw
-----+--------------------------------------------------+--------
49|The Whatkeez | 0
(1
row)

The table was not changed between the queries.

The result seems to depend upon whether or not the next letter of "name"
is a 'z'. I had the same effect with 'Gazze, Max'.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:

I hope I gave one!
