job stalls with (END) - postgresql

Question

I'm trying to set up two databases on travis but it just stops halfway the before_install stating:
(END)
No output has been received in the last 10 minutes, this potentially indicates a stalled build or something wrong with the build itself.
The build has been terminated
eg https://travis-ci.org/B3Partners/brmo/builds/85746119
my yml is the following:
language: java
sudo: false
branches:
only:
- travis-integration
addons:
postgresql: "9.3"
jdk:
# - openjdk6
# - openjdk7
- oraclejdk7
# - oraclejdk8
matrix:
fast_finish: true
cache:
directories:
- $HOME/.m2
before_install:
# STAGING
- psql --version
- psql -U postgres -c 'create database staging'
- psql -U postgres -c 'create database rsgb'
- psql -U postgres --list
# set up RSGB
- psql -U postgres -d rsgb -c 'create extension postgis'
- psql -U postgres -d rsgb -f ./datamodel/generated_scripts/datamodel_postgresql.sql --single-transaction --echo-all
# - psql -f ./datamodel/utility_scripts/111a_update_gemeente_geom.sql -U postgres -d rsgb --single-transaction
# - psql -f ./datamodel/utility_scripts/113a_update_wijk_geom.sql -U postgres -d rsgb --single-transaction
install:
# install all dependencies + artifacts without any testing
- mvn install -Dmaven.test.skip=true -B -V -fae -q
before_script:
# dit dient na afloop van de 'install' gedaan te worden omdat de staging DB sql gegenereerd wordt door Hibernate
- psql -U postgres -d staging -f ./brmo-persistence/target/ddlscripts/create-brmo-persistence-postgresql.sql --single-transaction
- psql -U postgres -d staging -f ./brmo-persistence/db/01_create_indexes.sql
- psql -U postgres -d staging -f ./brmo-persistence/db/02_insert_default_user.sql
- psql -U postgres -d staging -f ./brmo-persistence/db/03_update_status_enum_value.sql
# run tests
script:
# run unit tests
- mvn -e test -B
# run integration tests
- mvn -e verify -B
after_success:
after_failure:
after_script:
notifications:
email: false
# on_success: [always|never|change] # default: change
# on_failure: [always|never|change] # default: always
and as you can see in the log it just stalls after a few psql calls.

I just spent about 3 hours troubleshooting this same issue and the problem is pretty simple once you understand why. psql is simply trying to page the output. There are multiple ways to disable the pager, but the solution I went with was to set the PAGER=cat environment variable in .travis.yml like so:
env:
- PGUSER=postgres
PAGER=cat
