207391bc54 Remove parent oid from find_children_oids result 
Since the parent table of a hypertable cannot contain
any rows including it in the plan is not necessary. PostgreSQL might
also not have good statistics for the main table as autoanalyze is
triggered by inserts which never happen to the main table, leading to
worse plans.

This patch adds a new guc enable_constraint_exclusion to disable
planner constraint exclusion. Constraint exclusion will not work with
cursors and WHERE CURRENT OF so the new guc will allow you to disable
that feature.

This patch also fixes constraint exclusion for JOINs and sort
optimization for queries with chunks_in.
