Copying original post:

The pg_qsort() in postgis' gserialized_gist_picksplit_2d() likely could substantially benefit from using ​https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=0a1f1d3cac6baaa3744b89336673caba702f7628 

Add sort_template.h for making sort functions.

Move our qsort implementation into a header that can be used to define
specialized functions for better performance and reduced duplication.

No, this patch is for sorts on a few known types, and the picksplit sorts on intervals.
