See the documentation to figure out what is the condition name that
matches with the SQL State you have:

http://www.postgresql.org/docs/9.4/interactive/errcodes-appendix.html

23503 foreign_key_violation

Also, you can see that you have two BEGIN, and it might be causing your
problem here, anyway I see no use for this construct, try removing one.
