Comment:

 In [changeset:"17307" 17307]:
 {{{
 #!CommitTicketReference repository="" revision="17307"
 Add costs to functions in the form of macros:
 _COST_LOW, _COST_MEDIUM, _COST_HIGH
 Macros are set in sqldefines.h.in and are switched
 on PgSQL version. Prior to PG12, costs should be
 small or nonexistent, to avoid SQL inlining issues.
 After Pg12, costs can be higher to hopefully
 force more parallelism in plans.
 Closes #4344
