My patch is hidden in a very long thread, so I thought letting more widely known that I'm proposing to add a new subdir "partitioning" under src/backend and src/include. TBH I think the new idea is better than our current arrangement where we have catalog/partition.c which is a dumping ground for all sorts of code.
Anyway, for anybody who hates the idea, please speak up quickly. https://postgr.es/m/20180406164139.jsdq6oylt2twdkwr@alvherre.pgsql -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
