* Add a Redshift dialect that inherits from Postgres. * Turn .index() and .dropIndex() into no-ops with warnings in the Redshift dialect. * Update the Redshift dialect to be compatible with master. * Update package.json * Disable liftoff cli * Remove the CLI * Add lib to the repo * Allow the escaping of named bindings. * Update dist * Update the Redshift dialect’s instantiation of the query and column compilers. * Update the distribution * Fix a merge conflict * Take lib back out * Trying to bring back in line with tgreisser/knex * Add npm 5 package-lock * Bring cli.js back in line * Bring cli.js back in line * Progress commit on redshift integration tests * Revert "Progress commit on redshift integration tests" This reverts commit 207e31635c638853dec54ce0580d34559ba5a54c. * Progress commit * Working not null on primary columns in createTable * Working redshift unit tests * Working unit and integration tests, still need to fix migration tests * Brought datatypes more in line with what redshift actually supports * Added query compiler unit tests * Add a hacky returning clause for redshift ugh * Working migration integration tests * Working insert integration tests * Allow multiple insert returning values * Working select integration tests * Working join integration tests * Working aggregate integration tests * All integration suite tests working * Put docker index for reconnect tests back * Redshift does not support insert...returning, there does not seem to be a way around that, therefore accept it and test accordingly * Leave redshift integration tests in place, but do not run them by default * Fix mysql order by test * Fix more tests * Change test db name to knex_test for consistency * Address PR comments * Sublime Text gitignore * Redshift does not support adding more than one column in alter table * Fix integration tests for redshift * Linter * Combine dialect test skip if clause
