Gitlab update overwrite psql/pg_dump everytime


I’m using gitlab with own postgres server, as pointed in documentation I’ve replaced “pg_dump” and “psql” with files from my postgres version. The problem is, gitlab replace them again after update, so next update will fail (because of “pg_dump” version mismatch). Is there are way to replace them permanently?

I’ve replaced the file in “/opt/gitlab/embedded/bin” , using Debian Jessie with postgres 9.4.
