Waiting for PostgreSQL 14 – SEARCH and CYCLE clauses

On 1st of February 2021, Peter Eisentraut committed patch:

SEARCH and CYCLE clauses 
 
This adds the SQL standard feature that adds the SEARCH and CYCLE
clauses to recursive queries to be able to do produce breadth- or
depth-first search orders and detect cycles.  These clauses can be
rewritten into queries using existing syntax, and that is what this
patch does in the rewriter.

Waiting for 9.2 – Trigger Depth

On 25th of January, Alvaro Herrera committed patch:

Add pg_trigger_depth() function
 
This reports the depth level of triggers currently in execution, or zero
if not called from inside a trigger.
 
No catversion bump in this patch, but you have to initdb if you want
access to the new function.
