I do not get these errors, neither with the patch file I still have
locally, or by saving the attachment from my original email. Are you
sure something in your download process hasn't converted it to Windows
line endings (\r\n), or otherwise mangled the whitespace?

The patch doesn't add any lines that end with quote-space-backslash.
As for the space before the quote, that is not necessary either, since the
next line starts with a space after the quote. Either way, the updated
version of the patch doesn't add any new lines with continuation after a
string constant, so the point is moot.

Ah, I was looking at the documentation for 13, but CURRENT_ROLE is only
allowed in this context as of 14. Fixed.

As you note, psql currently doesn't currently tab-complete IF NOT EXISTS
for any command, so that would be a subject for a separate patch.

I did an audit of all the uses of Query_for_list_of_roles, and there
turned out be several more that accept CURRENT_ROLE, CURRENT_USER and
SESSION_USER that they weren't tab-completed for. I also renamed the
constant to Query_for_list_of_owner_roles, but I'm not 100% happy with
that name either.

The tab completion code for DROP is generic for all object types (see
the words_after_create array and the create_or_drop_command_generator
function), so that should be done genericallly, and is thus outside the
scope for this patch.
Thanks for the review. Updated patch attached, with the CURRENT/SESSION
ROLE/USER changes for other commands separated out.
