core: Fix db upgrade in PostgreSQL 8.x PostgreSQL 8.x and 9.x have a different behaviour regarding when inline SQL queries in PL/pgSQL code is evaluated (see http://wiki.postgresql.org/wiki/What%27s_new_in_PostgreSQL_9.0#PL.2FpgSQL_changes_which_may_cause_regressions). The current problem in upgrading the database in PostgreSQL 8.x is the min_refresh_rate column added in 03_02_0440_materialized_views_extensions.sql. The relevant parts of current flow (before the patch): 1. pre_upgrade script 30 creates the materialized_views table 2. materialized view functions are created 3. [various upgrade scripts] 4. 03_02_0440_materialized_views_extensions.sql - add a column to materialized_views. In 8.x variants, stage (2) will fail since the function can not compile due to the missing column. This patch changes the flow as follows: 1. pre_upgrade script 30 creates the materialized_views table 2. pre_upgrade script 40 adds the missing column 3. materialized view functions are created 4. [various upgrade scripts] Note that the original dbscripts/upgrade/03_02_0440_materialized_views_extensions.sql is preserved for backwards compatibility. Since it is reentrant (the column is only created if it did not previously exist), this is the safest way to go.
