Hello
I'm interesting in a partial index for a rows that aren't older than 6
mounts, something like the sentence below:
/ CREATE INDEX name_for_the_index ON table (the_column_of_type_date)
WHERE ( the_column_of_type_date > (current_date - interval '6
month')::date );/
But this is not posible, I receive the next error:
/ERROR: functions in index predicate must be marked IMMUTABLE/
So, what is the best solution for my problem?
Thank you,
Gustavo
