Tab completion didn't work for :{?<var>} and I noted that the same problem
would arise for :{+ or :{{ (and tab completion would be more important
here). So I fixed that on:

https://www.postgresql.org/message-id/flat/CAGRrpzZU48F2oV3d8eDLr=4TU9xFH5Jt9ED+qU1+X91gMH68Sw@mail.gmail.com

Would be great to have the above fix reviewed/committed to keep making
progress here.

Besides that, since :{ is already sort of a prefix for psql functions, how
about having `:{file(<filename>)}`? That would be clearer than :{+ or :{{.

Best regards,
