Fwd: Extending range type operators to cope with elements

> So yes, I've had a need for those operators in the past. What I don't
know is whether adding these functions will be worth the catalog clutter.

The operators are tested and running within MobilityDB. It concerns lines
231-657 for the C code in file
https://github.com/ULB-CoDE-WIT/MobilityDB/blob/master/src/rangetypes_ext.c

and lines 32-248 for the SQL code in file
https://github.com/ULB-CoDE-WIT/MobilityDB/blob/master/src/sql/07_rangetypes_ext.in.sql

Since you don't really use PR, please let me know whether I can be of
any help.

Regards
Esteban
