I am sorry for this but I do not know how else to communicate what is apparently happening: This is a portion of the log for the most recent run that exhibits the problem: ... 2009-07-10 15:59:17 EDT hll_theheart_test 216.185.71.24(49133) hll_theheart_db_admin : LOG: 00000: duration: 0.446 ms statement: INSERT INTO "currencies" ("is_invoicable", "is_payable", "changed_by", "created_by", "premium_factor", "discount_factor", "effective_from", "currency_name", "superseded_after", "changed_at", "currency_code", "created_at") VALUES('f', 'f', E'not available', E'not available', 0.9, 1.1, '1785-07-06 04:56:02.000000', E'United States Dollar', NULL, '2009-07-10 19:59:17', E'USD', '2009-07-10 19:59:17.634473') That seems a valid insert. 2009-07-10 15:59:17 EDT hll_theheart_test 216.185.71.24(49133) hll_theheart_db_admin : LOCATION: exec_simple_query, postgres.c:1105 2009-07-10 15:59:17 EDT hll_theheart_test 216.185.71.24(49133) hll_theheart_db_admin : LOG: 00000: duration: 0.172 ms statement: SELECT currval('currencies_id_seq') 2009-07-10 15:59:17 EDT hll_theheart_test 216.185.71.24(49133) hll_theheart_db_admin : LOCATION: exec_simple_query, postgres.c:1105 2009-07-10 15:59:17 EDT hll_theheart_test 216.185.71.24(49133) hll_theheart_db_admin : LOG: 00000: duration: 0.067 ms statement: RELEASE SAVEPOINT active_record_1 This seems ok but the absence of proof does not ensure the absence of error. If the insert failed would I see this fact reflected in a log entry? 2009-07-10 15:59:17 EDT hll_theheart_test 216.185.71.24(49133) hll_theheart_db_admin : LOCATION: exec_simple_query, postgres.c:1105 2009-07-10 15:59:17 EDT hll_theheart_test 216.185.71.24(49133) hll_theheart_db_admin : LOG: 00000: duration: 0.782 ms statement: SELECT * FROM "currencies" The client program that receives this result reports that there are no rows returned.
