Обсуждение: pgsql: Refactor the internal GIN B-tree interface for forming a downlin

Refactor the internal GIN B-tree interface for forming a downlink.

This creates a new gin-btree callback function for creating a downlink for
a page. Previously, ginxlog.c duplicated the logic used during normal
operation.
