Support: Generalize one more use case into support.util.refresh_table

[amotl]

Suggestion

@seut suggested another improvement at #28 (review):

I think I'd prefer moving this quoting logic into the refresh_tablefunction, by change it's signature to consume an optional schema. This would avoid that it will be called with unquoted or invalid relation names.

Status

This patch refactors the auxiliary logic into support.util.refresh_table, but doesn't do anything else yet, in order not to complicate the interface too quickly/early.

Q&A

Maybe I am currently not seeing the spot for important improvements, which should be done right from the start: So, please advise if you still would like to introduce an optional schema name as function argument, and also please suggest further improvements you would like to see in this area.

thx!
I think your approach with concrete argument signatures is also fine and eliminates the need for an optional table_schema argument.
