I might trigger a very long running query.
Consider doing something like:
get all headernames starting with 'x-':
select id from dbmail_headername where headername like 'x-%';
for each of those ids:
begin;
delete from dbmail_headername where id=<id>;
commit;
but do not do:
select from dbmail_headername where headername like 'x-%';
because that will run a very long time, and will trigger a write-lock on
both the dbmail_headername and dbmail_headervalue tables, blocking
insertion of new messages.
