2c6594edca Properly print the SQL server error string in the log message. 
On a Debian + PostgreSQL 9.4 system I had a hard time getting the
exporter to work. It looks like I was running into some authentication
issues that weren't logged by sql.Open(), but by sql.DB.QueryRow().

This change extends the warning generated by the call to
checkMapVersions() to also print the error message generated by
sql.DB.QueryRow().

3ead0f9aff Add a test case to detect regression on issue fixed by PR #39. 
Related issue is #38. Time to start expanding functional test coverage since
the integration tests missed this.

045ae96430 Implement the compileable source code of the basic integration test suite. 
This is the first step in moving the integration test suite to a more
reliable Golang based one.

a95fad8d1e Refactor scrape() to break out the major components. 
This puts us on the road to dropping the bash tests and doing it all in
Go.

f554139279 Add pg_static synthetic key to collect Postgres version. 
Similar to the node_exporter, this key is synthetic and used to create
a constant metric which records the version strings of PostgreSQL in its
labels.

c00d3fb6e7 Revert PR #23 which broke replication stats. 
This PR is not general to all versions of postgres, and in the worst case
meant the query returned nothing.

Closes #30 and shows we need a test case.

6f2f9890f7 Change default port to 9187. 
This is the postgres_exporter WIP port for Prometheus and avoids the
by default collision with the nginx_exporter.

Closes #22.

8cca2a59a5 Add docker based integration test suite. 
This simply pulls and runs postgres against a number of versions and checks
that we can successfully connect to it.

2a08787a90 Compiling version of the postgres_exporter. 
This is based on the mysqld_exporter, but drastically changes how metrics are
discovered and enumerated since postgres already very closely follows the
Prometheus format.
