The following documentation comment has been logged on the website:

Description:

https://www.postgresql.org/docs/current/functions-admin.html

pg_partition_root ( regclass ) → regclass
Returns the top-most parent of the partition tree to which the given
relation belongs. Returns NULL if the relation does not exist or is not a
partition or partitioned table.

"does not exist" is not correct description, if table does not exist, we'll
get an error, not NULL:

EXAMPLE:
SELECT * FROM pg_partition_root( 'nonexisting_table' );

RESULT:
SQL Error [42P01]: ERROR: relation "nonexisting_table" does not exist
Position: 34
