I suggest removing validate_sync_standby_slots() entirely since there
isn’t much left in it.

The below logic currently in validate_sync_standby_slots() to parse
the list of slots can be directly moved into
check_synchronized_standby_slots().

/* Verify syntax and parse string into a list of identifiers */
ok = SplitIdentifierString(rawname, ',', elemlist);

if (!ok)
GUC_check_errdetail("List syntax is invalid.");
