Mohit Sabharwal commented on HIVE-8374:
---------------------------------------
Instead of having the user supply an option dependent on Postgres version,
changed to the patch to automatically run a "pre-upgrade" script that creates
the language, but any error is ignored.
Kept the dbOpts option as that is useful when we add any db specific options.
> schematool fails on Postgres versions < 9.2

> The upgrade script for HIVE-5700 creates an UDF with language 'plpgsql',
> which is available by default only for Postgres 9.2+.
> For older Postgres versions, the language must be explicitly created,
> otherwise schematool fails with the error:
> {code}
> Error: ERROR: language "plpgsql" does not exist
> Hint: Use CREATE LANGUAGE to load the language into the database.
