APT whitelist request for postgresql-10 in trusty

[chosak]

Resubmission of #4255. Hoping that the addition of the PG APT repo at travis-ci/apt-source-safelist@e043c18#diff-eb3790820e97ba4b0dd22623188e706aR378 will allow for this package to be whitelisted.

Ran tests, but could not found source package. Either the source package for postgresql-10 does not exist, or the package needs an APT source. If you wish to add an APT source, please follow the directions on https://github.com/travis-ci/apt-source-whitelist#source-approval-process. Build results: https://travis-ci.org/travis-ci/apt-whitelist-checker/builds/417551649.
