Since you change default version from 1.0 to 1.1 you need to supply the
sslinfo--1.1.sql script. You also need to supply a sslinfo--1.0--1.1.sql
script which enables updates from version 1.0 to 1.1.

(The test for the upgrade is to initdb 9.4, and in some database install
the sslinfo extension; then pg_upgrade to a version with your patch. In
the database with the extension then try to upgrade it to 1.1.)

Please use C type bool not int when that's what the code means.
