Hi all
Is there an LC_COLLATE setting, or any other method, which allows all data
in a database to be treated in a case-insensitive manner?
I have two scenarios in mind. There are workarounds for both of them, but it
would be nice if they were not necessary.
1. In a UNIQUE column, I would like a value of 'a' to be rejected if there
is already a value of 'A'. Workaround - create a unique index on
LOWER(col_name).
2. I would like WHERE col_name = 'x' and WHERE col_name LIKE 'x%' to find
'X' and 'X1'. Workaround - WHERE LOWER(col_name) = 'x' and WHERE col_name
ILIKE 'x%'.
TIA

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
