I've run across a strange problem with PG 8.3.3 not using indexes on a
particular table after building the table during a transaction.
This may be a HOT side-effect ... is pg_index.indcheckxmin set for
the index?
Yep, sure enough, the 'act' table's indexes have it set and jefftest and jefftest2's indexes do not.
select c.relname,i.indcheckxmin from pg_class c, pg_index i WHERE i.indexrelid = c.oid AND c.relname IN ('act_act_usr_id', 'act_arrived', 'act_closing', 'act_place');
relname | indcheckxmin
----------------+--------------
act_closing | t
act_act_usr_id | t
act_place | t
act_arrived | t
(4 rows)
consdb=# select c.relname,i.indcheckxmin from pg_class c, pg_index i WHERE i.indexrelid = c.oid AND c.relname IN ('jefftest2_jefftest_usr_id', 'jefftest2_arrived', 'jefftest2_closing', 'jefftest2_place');
relname | indcheckxmin
---------------------------+--------------
jefftest2_jefftest_usr_id | f
jefftest2_place | f
jefftest2_arrived | f
jefftest2_closing | f
