Is your feature request related to a problem? Please describe.
If we have different queries within the same script, if we execute, they will go serial (one by one), but if you want them to run in parallel, you need to open different scripts.

Describe the solution you'd like
Would it be possible to execute all the queries in parallel?

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
Using postgres connector, I want to insert data into different tables, at the same time, and I want to run them in parallel. e.g:

INSERT INTO tpcds.web_returns
SELECT * FROM tpcds_ext.foreign_web_returns;

INSERT INTO tpcds.web_sales
SELECT * FROM tpcds_ext.foreign_web_sales;
