[sqlite] Disable custom collate

[JP]

Hi,

I created a table with a field and index that uses a custom collation 
function MYCOLLATE.

The problem I am having is portability, I cannot perform simple selects 
on the table on other sqlite based applications since the custom 
collation function is not available.

Does anybody out ther know of a PRAGMA or directive or method to disable 
the usage of a custom collation once created? or a way to drop it?
