Support jsonb data type with Postgres database

[pascalsem]

Hello,

In my organization we are using dbfit version 3.2.0 and added support to jsonb data type in order to enable data insertion on such table columns.

Made same modifications on this pull request than in 3.2.0 PostgresEnvironment class.

As I am not using Gradle, I cannot perform tests from my workstation .... and have been done with dbfit and a PostgreSQL 9.6.10 database. Sorry for that.

The test page looks like this (assuming connection is established with db) :

!|Execute|CREATE TABLE anything(field JSONB)|

!|Inspect Query|SELECT * FROM anything|

!|Insert |anything |
|field |
|!-{"field" : "value"}-!|

• a parser for PGobject class

Hi @pascalsem, thank you for this contribution! Are you able to add some tests - they will run automatically on CI server PostGres, you don't need PostgreSQL locally to run them.

In progress :)

Hello @javornikolov I have updated pull request with missing components and tests to verify it works. It runs good in my local workstation (postgres 13.2 installed) but I can't figure out why it is failing in TravisCI. Is there any way for me to troubleshoot the execution ? Thanks :)

Ran ./gradlew :dbfit-java:postgres:integrationTest

Hi @pascalsem, maybe that from Travis CI build log would be helpful enough:

Perfect, thanks a lot I will be fixing those and run the task :)

Hello again @javornikolov, I think I figured out why build is failing on Travis and not in local. Json data types in postgresql appeared since 9.2 but properly supported in 9.4 (https://www.postgresql.org/docs/9.4/datatype-json.html).

So, do you think we can afford to upgrade version of postgresql to at least 9.4 ? It seems I could try with this documentation https://docs.travis-ci.com/user/database-setup/

Update : changed travis postgresql engine to 9.6

We better use explicit imports

@javornikolov let me know if you think it's worth squashing some of these commits.

Thanks, @MMatten, I already merged it keeping the original commits.
