How to delete multiple rows from multiple joined tables - Mailing list pgsql-sql

I'm trying to use SQL to delete multiple rows from multiple tables that are
joined together.  From what I've seen delete can only delete from a single
table, which is OK because I can just do separate deletes for each table.
But the problem is how do I specify which rows to delete?  For example:

Table A is joined to Table B
Table B is joined to Table C

I want to delete all rows in table C & B that correspond to a row in Table
A.  Here's my exact SQL which actually deletes all the rows:

delete from monitorstatusitemx where monitorx.namex='STRESS_TEST' and
monitorstatusx.jdoidx = monitorstatus_statusitemsx.jdoidx and
monitorstatus_statusitemsx.statusitemsx =
monitorstatusitemlistd8ea58a5x.jdoidx and
monitorstatusitemlistd8ea58a5x.statusitemlistx = monitorstatusitemx.jdoidx

(It's a little ugly because I'm using JDO which generates the schema.
Unfortunately deletes with JDO are very slow so I need to use SQL for this.)
