Doc: clarify the conditions of usable indexes for REPLICA IDENTITY FULL tables.
Commit 89e46da5e allowed REPLICA IDENTITY FULL tables to use an index on the subscriber during apply of update/delete. This commit clarifies in the documentation that the leftmost field of candidate indexes must be a column (not an expression) that references the published relation column. The source code comments are also updated accordingly.
