PlatformIO UART filter for Rd-03E (AI-Thinker)

	"""
	Custom PlatformIO filter for parsing Rd-03E radar sensor data from UART.

	This filter is designed to process UART frames from the Rd-03E gesture recognition radar sensor.
	It extracts distance and gesture information from the sensor's output and formats it for easy reading.

	Usage:
	1. Place this file in the `monitor` directory of your PlatformIO project as `filter_rd03e.py`
	2. Run the PlatformIO device monitor with the filter enabled:
	`platformio device monitor -b 256000 -p /dev/ttyUSB0 -f rd03e`

Postgres "lock trees" analysis: the forest of trees of blocked and blocking sessions

	-- https://gitlab.com/-/snippets/1890428
	-- The query shows "the forest of trees" of blocked and blocking sessions with the corresponding queries. It helps to understand, which session is being blocked by which one, and what is "the depth" of the lock chain.
	-- Use it to find the "roots" of trees, then use pg_cancel_backend(pid) or pg_terminate_backend(pid) to get rid of blockers and release the locks.
	-- Derived from DataEgret's locktree.sql (https://github.com/dataegret/pg-utils/blob/master/sql/locktree.sql)
