# Postgres uses discrete range types for int4range, which means
|
|
# (1..2) is stored as (1...3).
|
|
#
|
|
# We use Range#max to work around this, which in the case above always returns 2.
|
|
# Be careful with using Range#end here, it could lead to unexpected results as:
|
|
#
|
|
# (1..2).end => 2
|
|
# (1...3).end => 3
