* refactor postgres, * adds a basic unit test module * first step towards a common utils module * set postgresql_db doc argument defaults to what the code actually uses * unit tests that actually test a missing/found psycopg2, no dependency needed * add doc fragments, use common args, ansible2ify the imports * update dict * add AnsibleModule import * mv AnsibleModule import to correct file * restore some database utils we need * rm some more duplicated pg doc fragments * change ssl_mode from disable to prefer, add update docs * use LibraryError pattern for import verification per comments on #21435. basically LibraryError and touching up its usage in pg_db and the tests.
