Description

Having typed an alias name in an ORDER BY or (SELECT) DISTINCT clause,
the alias was not taken account of, and the completion simply listed all
columns. This change fixes that, and makes the autocompletion behave the
same as in SELECT and WHERE clauses.

Thanks for taking the time to make pgcli better. Sorry I haven't had time to look into this. I won't have time till end of this week, but if none of the other core devs have reviewed it by then, I'll take a look. Sorry about the delay.

This looks good, and seems to work as expected - I tried it out on a few cases. I don't think that def table_reference is needed though.

TableReference instantiation is already a one-liner. What's the point of wrapping it into a function?

On reflection, probably none, I think I added it before I did a bunch of line-wrapping. Of course, one can avoid passing a few parameters since table_reference has default parameters, but I don't think the method pulls its weight, I'll remove it.

Wouldn't be a good PR without them...!

No worries about taking your time @amjith! Thanks for the review @j-bennet - I've addressed the comment and squashed it into one commit since it was a small tweak (I hope that's ok for this project!)

@owst Also, the line in changelog:

Completion suggestions for ORDER BY and DISTINCT clauses now take account of partially-typed identifiers as per WHERE.

is not very clear. I would suggest something like:

Fixed completions after ORDER BY and DISTINCT when using table aliases.

Yeah, fair enough, I'm certainly not wedded to the current wording. The only thing is "fixed" to me suggests it was "broken" before, when I think it was just a missing feature. Perhaps

Completions after ORDER BY and DISTINCT now take account of table aliases.

?
