Can't select wb_health_population columns using Postgres

• I have checked the superset logs for python stacktraces and included it here as text if any
• I have reproduced the issue with at least the latest released version of superset
• I have checked the issue tracker for the same issue and I haven’t found one similar

Superset version

0.26.0 - following docker-compose instructions

Expected results

Be able to run World Bank dashboard.

Actual results

I’m not able to run any query that state particular wb_health_population column as in Postgres columns created with " " should be referenced this way as well. The exact same problem as here: https://stackoverflow.com/questions/24253814/cant-select-an-existing-column-in-postgresql

2018-09-29 14:00:38,127:INFO:root:SELECT SP_POP_TOTL
FROM wb_health_population
LIMIT 1
2018-09-29 14:00:38,128:ERROR:root:column "sp_pop_totl" does not exist
LINE 1: SELECT SP_POP_TOTL
               ^
Traceback (most recent call last):
  File "/home/work/incubator-superset/superset/sql_lab.py", line 185, in execute_sql
    db_engine_spec.execute(cursor, query.executed_sql, async_=True)

    cursor.execute(query)
psycopg2.ProgrammingError: column "sp_pop_totl" does not exist
LINE 1: SELECT SP_POP_TOTL

Steps to reproduce

Follow docker-compose instructions and try to render WB dashboard.

I hope that it’s not because of the fact I’m still using 0.26. Either way I would be very happy to help with improving test data set generation or with Docker images maintenance.

Changing the column name to include double quotes works. SELECT country_name AS country_name, SUM(SP_POP_TOTL) AS “sum__SP_POP_TOTL” FROM wb_health_population WHERE year >= ‘2014-01-01 00:00:00’ AND year <= ‘2014-01-02 00:00:00’ GROUP BY country_name ORDER BY “sum__SP_POP_TOTL” DESC LIMIT 50000

to

SELECT country_name AS country_name, SUM(“SP_POP_TOTL”) AS “sum__SP_POP_TOTL” FROM wb_health_population WHERE year >= ‘2014-01-01 00:00:00’ AND year <= ‘2014-01-02 00:00:00’ GROUP BY country_name ORDER BY “sum__SP_POP_TOTL” DESC LIMIT 50000

This is a Postgres-specific issue related to column names - Postgres converts all column names to lower case unless they are quoted. So, expected behaviour, but something we can account for. Nope, looks a bit more complicated, and may have to do ‘MetricsControl’. I’m working on a PR for this.
