Autocomplete not working for "events" table if unquoted

[owst]

Description

We have a table named events. Autocomplete doesn't work in query involving this table (at least for a JOIN condition and a SELECT column), unless I quote the table name.

Reproduction

postgres@localhost:postgres> CREATE TABLE events (description text);
CREATE TABLE
Time: 0.012s

Then

postgres@localhost:postgres> SELECT descri* FROM events; 

Cursor at *, having just typed i the completions I see are:

pg_describe_object()                    function  
col_description()                       function  
obj_description()                       function  
shobj_description()                     function  
binary_upgrade_set_record_init_privs()  function  
describe                                keyword   

If I change s/events/"events"/ and retype the i:

postgres@localhost:postgres> SELECT descri FROM "events"; 

then I see:

description                             column    
pg_describe_object()                    function  
col_description()                       function  
obj_description()                       function  
shobj_description()                     function  
binary_upgrade_set_record_init_privs()  function  
describe                                keyword   

as expected.

I'm using Vi-mode, if that matters (I don't think it does). Is this expected, or is there something special about the table name events? Interestingly, if I call the table not_events I don't need to quote the table name for the columns to autocomplete.

Having dug into this, sqlparse is (incorrectly, for Postgres) treating events as a keyword, rather than an identifier. I've followed up on a promising-sounding PR that would allow us to use sqlparse in "Postgres" mode, where events wouldn't be considered a keyword, but for now, I don't see an easy way to fix this issue
