EXPLAIN and FK references?

[Ron <ronljohnsonjr@xxxxxxxxx>]

    Pg 12.11
    
    Deletes are slow in one table with many indices and FK references. 
    That's not surprising, but it's VERY slow, and I'm trying to
    figure out why.
    
    Is there any EXPLAIN option which shows what "query plans" Pg is
    using when checking FK references (index scan, seq scan, etc) during
    deletes (and inserts and updates)?
