[Dbix-class] lower on column and query

[Moritz Onken]

Interestingly, I thought about the same problem yesterday,
I was looking at the difference of LIKE in postgres and mysql. Seems  
like LIKE in postgres is case sensitive and in mysql it's not. So you  
have to use ILIKE in postgres to get the same behaviour as LIKE in  
mysql.
To make an application independent from its DBMS you need to do  
soemthing like "lower(field) LIKE lower(query)" (as emmanuel said).

And I have no idea how I can append a whitespace % to that  
lower(query) part :-)
