Changes ListClosedWorkflow result ordering for SQL-based visibility s…
Browse files Browse the repository at this point in the history 
…tores to be based off of workflow close time (#578)

This PR fixes the following issues:

SQL stores were using the Workflow Open Time instead of the Close Time for pagination, which is not aligned with Cassandra and is not the intention.

The SQL store pagination logic had a bug where the tie-breaker logic of using run_id for two rows with the same close_time was not implemented properly.

The SQL store pagination logic had a bug where it was using the MinStart time instead of the MaxStart time for pagination purposes (to be confirmed as to whether this is truly a bug or not, but it does appear that way)

Fixes Makefile so that schema installation for MySQL / Postgres functions properly.

Fixes Postgres username / password in postgres development environment.

Adds appropriate MySQL/Postgres indexes for querying by close_time
