[open-ils-commits] r18678 - in branches/rel_2_0/Open-ILS/src/sql/Pg: . upgrade (gmc)

[svn at svn.open-ils.org]

Author: gmc
Date: 2010-11-10 08:19:03 -0500 (Wed, 10 Nov 2010)
New Revision: 18678

Added:
   branches/rel_2_0/Open-ILS/src/sql/Pg/upgrade/0462.schema.no-truncate-during-bib-view-refresh.sql
Modified:
   branches/rel_2_0/Open-ILS/src/sql/Pg/002.schema.config.sql
   branches/rel_2_0/Open-ILS/src/sql/Pg/reporter-schema.sql
Log:
do not use TRUNCATE when refreshing reporter.materialized_simple_record

Previous behavior would break Slony replication after doing a
bib load.  Since a deletion is slower than a truncate, if you're
not using Slony replication, you may prefer to truncate rmsr
prior to calling reporter.enable_materialized_simple_record_trigger.
