Re: Custom Operator for citext LIKE predicates question

Good points. At least on the limited testing we did, we were able to get the same answer back with both executions; at least for the use cases we tested. 
We are still doing more thourough testing.
This is an application that is been ported from MS SQL server to postgres and apparently the migration dba team determined citext was the way to go to maintain MSSQL existing usage of the data in the columns.

To me, "work" includes "get the right answer".  I do not think you
are getting the same answers that citext would normally provide.
If you don't care about case-insensitivity, why don't you just
use plain text?
