Would this help?:

http://www.postgresql.org/docs/9.5/interactive/app-psql.html
"-1
--single-transaction

     When psql executes a script, adding this option wraps BEGIN/COMMIT
around the script to execute it as a single transaction. This ensures
that either all the commands complete successfully, or no changes are
applied.

     If the script itself uses BEGIN, COMMIT, or ROLLBACK, this option
will not have the desired effects. Also, if the script contains any
command that cannot be executed inside a transaction block, specifying
this option will cause that command (and hence the whole transaction) to
fail.
