Another question on indexes (drop and recreate) - Mailing list pgsql-performance

Hi,


I have another question regarding indexes.


I have a table with a lot of indexes on it.  Those are needed to
perform my searches.

Once a day, a bunch of records is inserted in my table.


Say, my table has 1.000.000 records and I add 10.000 records (1% new)

What would be faster.


1) Dropping my indexes and recreating them after the inserts

2) Just inserting it and have PG manage the indexes


Met vriendelijke groeten,

Bien à vous,

Kind regards,
