This is (a) probably not a bug, and (b) entirely undiagnosable from
the amount of information you've given.

For help with asking answerable questions, see

https://wiki.postgresql.org/wiki/Slow_Query_Questions

(But, FWIW, a common reason for slow deletes is a foreign key
referencing this table, where the referencing column is unindexed.
Or maybe the delete was just blocked on somebody's exclusive lock?)
