Added:
trunk/Open-ILS/src/sql/Pg/upgrade/0267.schema.identifier-search-class-improvement.sql
Modified:
trunk/Open-ILS/src/sql/Pg/002.schema.config.sql
trunk/Open-ILS/src/sql/Pg/030.schema.metabib.sql
trunk/Open-ILS/src/sql/Pg/950.data.seed-values.sql
Log:
add ISBN 10/13 index normalizer (requires ISN postgres contrib module); adjust index definition xpath so it actually works; generalize indexing trigger function so it does not have to know about search classes before hand
