Thread: pgsql: Add missing NULL check when building Result Cache paths
Add missing NULL check when building Result Cache paths Code added in 9e215378d to disable building of Result Cache paths when not all join conditions are part of the parameterization of a unique join failed to first check if the inner path's param_info was set before checking the param_info's ppi_clauses. Add a check for NULL values here and just bail on trying to build the path if param_info is NULL. lateral_vars are not considered when deciding if the join is unique, so we're not missing out on doing the optimization when there are lateral_vars and no param_info.
