A Note on Components ==================== Almost all packages in the apt.postgresql.org repository, including the PostgreSQL server packages for all versions, are located in the "main" component (aka directory). The other N.N components here (like "9.2") merely serve as stowage for the non-default-version library packages built from server packages. The libpq packages from the older PostgreSQL versions live here, as well as those from beta and devel branches. The libpq packages from the newest stable PostgreSQL version live in "main" as well. This is why the N.N directories here only contain few package, and most of the time there will not even be a directory for the "current" stable PostgreSQL version. To use the repository, follow the instructions at https://wiki.postgresql.org/wiki/Apt People using the apt.postgresql.org repository should usually only be concerned about using the "main" component, unless installing beta or devel versions of the PostgreSQL server packages: https://wiki.postgresql.org/wiki/Apt/FAQ#I_want_to_try_the_beta_version_of_the_next_PostgreSQL_release
