But I keep getting a parser error. Am I not allowed to use JOINs in a
DELETE statement, or am I just fat-fingering the SQL text

You have to tell it what table you are deleting from. Select * from A
join B is both tables. What you want to do is fix the where clause.
DELETE FROM
Re: [PERFORM] Are JOINs allowed
with DELETE FROM

Thank you for the link to the documentation page. I forgot to mention that
we're still using version 7.3. When I checked the 7.3 documentation for
DELETE, there was no mention of being able to use fields from different
tables in a WHERE clause.
Many thanks to Gaetano Mendola and Tom Lane for the hints about using
fields from other tables in a DELETE's WHERE clause. That was the magic
bullet I needed, and my application is working as expected.
