* Feature #2731: added postgres import and dump
* Feature #2731: be more permissive of arguments
```
hacking/test-module -m ./ppostgresql_db.py -a "db=example state=dump target=/tmp/out"`
```
failed previously since host, user, and port were required as keywords
in the pg_dump / pg_import methods.
* Feature #2731: fixed doc string for validate-modules
```
$ ansible-validate-modules database/postgresql/
```
now passes.
* Feature #2731: disable 'password' for dump/restore
* Feature #2731: bump added version to 2.3
* Feature #2731: replace db_import with db_restore
* Feature #2731: add missing version description
* Feature #2731: fix 'state' description
* Feature #2731: fix pep8 issues
* Feature #2731: put state documentation in a single string
* Bump added version from 2.3 to 2.4
* Fix pep8 and pylint errors
* Attempt yaml formatting of documentation string
* Add integration tests for postgres_db:dump/restore
* Update dump/restore logic to support new kw-args
Also attempt to support password; integration tests are
still failing.
* Revert to postgres user for dump/restore
Passing PGPASSWORD is not working for subprocesses. For the
moment, reverting to the strategy of failing if login_password
is set and using `postgres` for all testing of dump/restore.
* Various cleanups to have tests passing
* Working tests for {sql,tar} x {,bz2,gz,xz}
* Use pg_user to support FreeBSD
* Revert login_ prefixes and re-enable password support
All `login_` keywords are mapped to their non-prefix versions
so the previous changes were effectively using `postgres` for
all actions. With the proper keywords, PGPASSWORD-passing to
the subprocess is now working.
* Optionally add password
environ_update doesn't handle None values in the
dictionary to be added to the environment. Adding
check.
* Quick fixes
* Refactor login arguments after fixes from pchauncey
The fixes introduced by pchaunchy pointed to further issues
(like no --dbname on PG<=9.2) with the login parameters. This
refactors them and adds further tests.
Note: this will still not pass integration tests due to a further
issue with pg_dump as a non-admin user:
pg_restore: [archiver (db)] Error while PROCESSING TOC:
pg_restore: [archiver (db)] Error from TOC entry 1925; 0 0 COMMENT EXTENSION plpgsql
pg_restore: [archiver (db)] could not execute query: ERROR: must be owner of extension plpgsql
* Introduce target_opts for passing limiting dumped/restored schemas
The current integration tests (PG version and template DBs) don't
permit a regular user (`{{ db_user1 }}`) access to plpgsql causing
restores to fail. By adding an option for passing arbitrary args to
pg_dump and pg_restore, testing is made easier. This also paves the
way for `-j` usage, once the PG version is bumped.

per comments on #21435. basically LibraryError and touching up its usage in pg_db and the tests.
