Other changes from the original PR:
- Changed time column to be time_sec to allow other time units in the
future and to be the same as MySQL
- Changed integration test to test the main Query method rather than
the private transformToTable method
- Changed the __timeSec macro name to __timeEpoch
- Renamed PostgresExecutor to PostgresQueryEndpoint
Fixes#9209 (the original PR)
* postgres: encrypt password on config page
With some other cosmetic changes to the config page:
- placeholder texts
- reset button for the password after it has been encrypted.
- default value for the sslmode field.

The generated queries when selecting multiple tags are incorrect. In
InfluxQL, `AND` has a higher precedence than `OR` so the condition:
WHERE "hostname" = 'server1' OR "hostname" = 'server2' AND time > now() - 5m
This is parsed as if it were:
WHERE "hostname" = 'server1' OR ("hostname" = 'server2' AND time > now() - 5m)
But the intention is to write a query like this:
WHERE ("hostname" = 'server1' OR "hostname" = 'server2') AND time > now() - 5m
This change modifies the generated query so it surrounds a query with
multiple conditions in parenthesis so it doesn't conflict with the time
expression in an unexpected way.
This is currently not an issue because InfluxDB doesn't actually
evaluate the condition for the time expression correctly. It just looks
through the AST for anything that looks like a time expression and then
assumes the proper format of `AND` was used rather than validating that
it was used correctly.
