Provide * autocompletion of all columns of a table

[tobias-haenel]

I would like to have autocompletion for * to add in all column names if the table can be uniquely identified:
(e.g. in select and update/insert with returning clause)

select
  *
from
  food;

should expand to

select
  id,
  column_a,
  column_b,
from
  food;

where id, column_a and column_b are all columns of the table food.

this would simplify capturing the current db schema state of a table into a sql query file.
later schema changes wouldn't break any queries or lead to unnecessary data transmission.

right now I need to enumerate all columns manually.
I would also be fine if a custom id/character to trigger where used to trigger this completion or to make it optional, so that is doesn't collide with the standard * usage.

thanks for you work on this urgently needed work in the ecosystem of LSPs and Postgres!
