The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/18/functions-admin.html 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
