[open-ils-commits] r18842 - in trunk/Open-ILS/src/sql/Pg: . upgrade (dbs)

[svn at svn.open-ils.org]

Author: dbs
Date: 2010-11-23 22:31:14 -0500 (Tue, 23 Nov 2010)
New Revision: 18842

Added:
   trunk/Open-ILS/src/sql/Pg/upgrade/0466.schema.asset-copy-add-create-date-index.sql
Modified:
   trunk/Open-ILS/src/sql/Pg/002.schema.config.sql
   trunk/Open-ILS/src/sql/Pg/040.schema.asset.sql
Log:
Add an index on asset.copy(create_date) for item-age browse

Running an item-age browse against a database with a reasonable
number of entries in asset.copy is dog-slow without an index
like this.
