  • Skip optimised #exist? query when #include? is called on a relation
    with a having clause

    Relations that have aliased select values AND a having clause that
    references an aliased select value would generate an error when
    #include? was called, due to an optimisation that would generate
    call #exists? on the relation instead, which effectively alters
    the select values of the query (and thus removes the aliased select
    values), but leaves the having clause intact. Because the having
    clause is then referencing an aliased column that is no longer
    present in the simplified query, an ActiveRecord::InvalidStatement
    error was raised.

    An sample query affected by this problem:

    Author.select('COUNT(*) as total_posts', 'authors.*')
          .joins(:posts)
          .group(:id)
          .having('total_posts > 2')
          .include?(Author.first)

    This change adds an addition check to the condition that skips the
    simplified #exists? query, which simply checks for the presence of
    a having clause.

    Fixes #41417

  • Increment postgres prepared statement counter before making a prepared statement, so if the statement is aborted
    without Rails knowledge (e.g., if app gets kill -9d during long-running query or due to Rack::Timeout), app won't end
    up in perpetual crash state for being inconsistent with Postgres.
