Hello Folks,
I will ask my question through an example:
1) I have table PROJECT that has a foreign key USER_ID references USER(ID)
2) I *don't* use USER_ID in a where clause so don't have to create indices for performance reason.
3) USER table's primary key *never* changes.
Q: Do I have to create an index for FK USER_ID to speed up updates to USER table rows?
Basically, is PG nice enough to understand that since a key is not updated, it need not check the integrity
constraints.
I am using PGSQL 7.1.3
Thanks.
