I do have a field for which I want to perform a join with some other field in another table using case without case sensitivity perhaps using ~*.
One of this fields may contain + characters or unbalanced parenthesis. Is there a way or some function that may mask out the regexp awareness of any of these characters if they appear the field values.
Should I need to write a function to escape each of these characters by placing a "\" character before it?
