Add tablespace filter

[ylacancellera]

In the list of tables, when hovering we know the tablespace
I believe it will help to have some toggles to select which tablespaces to select, to only see tables from a specific tablespace

Yes @ylacancellera ,
The ability to filter based on different criteria is an important feature request. The UI may need some tweaks for that. I have been thinking about it for some time.
As a faster and quicker fix to address this need, let me add custom SQL which can be executed on the top of pg_gather data

@ylacancellera, the commit db5b76e should address this requirement.
It will now be easy to extract all the information presented in the "Tables" section.
Will be included in release of version 32
