What is the fastest null WHERE - Mailing list pgsql-performance

  Hello,

  While writing web application I found that it would
be very nice for me to have "null" WHERE clause. Like
WHERE 1=1. Then it is easy to concat additional
conditions just using $query . " AND col=false" syntax.

  But which of the possible "null" clauses is the fastest
one?

  Thanks,
