Hi,
with 9.2.2 I can see harmless cosmetic defect while dumping/restoring database with postgis extension.
Steps to reproduce:
- create new database;
- CREATE EXTENSION IF NOT EXISTS postgis WITH SCHEMA public;
- backup it;
- create new database and restore it from this new backup.
It produces 3 errors while executing these 3 statements:
CREATE RULE geometry_columns_delete AS ON DELETE TO geometry_columns DO INSTEAD NOTHING;
CREATE RULE geometry_columns_insert AS ON INSERT TO geometry_columns DO INSTEAD NOTHING;
CREATE RULE geometry_columns_update AS ON UPDATE TO geometry_columns DO INSTEAD NOTHING;
All 3 errors are similar to this:
pg_restore: [archiver (db)] Error from TOC entry 3874; 2618 396850 RULE geometry_columns_delete postgres
pg_restore: [archiver (db)] could not execute query: ERROR: rule "geometry_columns_delete" for relation "geometry_columns" already exists
Command was: CREATE RULE geometry_columns_delete AS ON DELETE TO geometry_columns DO INSTEAD NOTHING;
This happens because in the beginning of backup file there is issued command
CREATE EXTENSION IF NOT EXISTS postgis WITH SCHEMA public;
which creates those rules.
Solution could be not to issue commands to create abovementioned rules, or issue 'CREATE OR REPLACE RULE' instead of 'CREATE RULE'.
As I understand these errors are harmless, I would say - cosmetic defects.
