[core] Export/import all stored scripts

Hi, we would like to get a migic button which exports all stored hive/impala/pig queries to zip archive with structure:
zip
/hive
my_favourite_hive_query.sql
/pig
the_dirtiest_pink_pig_script.pig
/e.t.c

The problem:
Right now we have 100+ stored queries and scripts
We need to migrate from default sqlite to postgre, and I need to ask all analysts to dump their scripts. I give 146% that some of them won't do it at all or will do it partially.
I would like to avoid data migration from sqlite to postgre. I didn't find some kind of automated tool and I don't want to invent the bycicle for this task.

Any teams migrating from default sqlite to postgre/mysql/.e.t.c. would need such functionality.
