Actually for searches lower will work.
But the other important aspect is 'inserts' which would result 2 rows if
the values are 'A' and 'a'. Intent here to have it case insensitive.
If CITEXT it will update the same row and works.
CITEXT is an alternative but was wondering if there is any other alt

You could build lower() indexes on any column you want to search CI
and lower()
Can case-insensitive collation help here?

Hi Karsten,
modifying user inputted data is not an option for me. I need to maintain the
original data. I had read about indexing on a lower function. This all seems a

You need to double-quote the object names that you don't want to be

Well, the rule is very simple, either always quote your identifiers, or
never quote them. If you always quote them, then you always need to
specify them in the same case. If you never quote them, then you always
get case-insensetivity.

To handle searching for a row based on a string, I will use
"LOWER(colname)
= 'x'" and "LOWER(colname) LIKE 'x%'". AFAICT, the second one is
equivalent
to "colname ILIKE 'x%'", provided I force 'x' to lowercase first.
I would strongly suggest you do this instead:
LOWER(colname) = LOWER('x')

Make sure that what ever 'red' might be is always lower case (you can pass
