New to Postgres and I have never seen this condition. We are getting test applications hanging on SELECT statements with a RowExclusiveLock. How can a SELECT cause a RowExclusiveLock?
relname | pid | mode | granted
--------------------------+-------+------------------+---------
sales_transaction_detail | 392 | RowExclusiveLock | t
sales_transaction_detail | 19077 | RowExclusiveLock | t
sales_transaction_header | 32661 | RowExclusiveLock | t
sales_transaction_header | 392 | RowExclusiveLock | t
sales_transaction_header | 19077 | RowExclusiveLock | t
pid | age | usename | query
-------+------------------+----------+----------------------------------------------------------------------------------
32661 | -07:42:39.289945 | postgres | UPDATE "sales_transaction_header" SET "create_datetime" = '2017-04-07T02:20:39.4
19077 | -07:42:15.976288 | postgres | SELECT "price_benefit"."id", "price_benefit"."create_datetime", "price_benefit".
392 | -07:01:44.121346 | postgres | SELECT "price_benefit"."id", "price_benefit"."create_datetime", "price_benefit".
