Hi CCHsu,

This looks useful, but it does overlap with my patch to add completion
for column and function names to SELECT -- see
https://commitfest.postgresql.org/18/1376/ . I have been quiet on
this as everyone was (and still is) busy with the 11.0 release.

I also have a patch for columns and functions after a comma in the
select list, but I've been even more quiet on that one.

We can try to combine them. It won't be as simple as your patch here,
unfortunately. Luckily the completions are active at mostly*
different times. Was the last word SELECT ? Offer a column or
function name. Otherwise offer FROM/INTO.

* note that FROM/INTO can also appear directly after SELECT!

Cheers,
Edmund
