Re: Add missing tab completion for VACUUM and ANALYZE with ONLY option

Looks good overall. However, after pressing Tab, ONLY appears in the completion list, but it doesn't autocomplete after typing the first letter.

In which case you noticed this?

Ah, I just tested it using these examples from the regression tests:

CREATE TABLE only_parted (a int, b text) PARTITION BY LIST (a);
CREATE TABLE only_parted1 PARTITION OF only_parted FOR VALUES IN (1);

ONLY doesn't autocomplete here because the table names begin with "only...", which conflicts with autocompletion—this was my oversight.

----------

Everything seems fine with the ANALYZE command autocompletion. Regarding VACUUM, I'm not entirely convinced we should provide autocompletion in every case. I'd prefer to keep the behavior from the v3 patch because the original intention behind adding the ONLY keyword was specifically for collecting statistics exclusively from parent tables. Therefore, autocompletion makes sense primarily for the ANALYZE case.

Any thoughts?
