See /usr/local/opt/postgresql-common/README.Debian to get started. The port a bit experimental, but it works. Postgresql-common is a port of the postgresql-common package from Debian, which contains programs that help manage these multiple versioned installations, and programs to manage multiple PostgreSQL instances (clusters). The PostgreSQL major versions that are still maintained upstream are expected to work, but anything beyond that is best-effort and YMMV. But note that over time, the oldest versions will stop building and/or running on newer operating system versions. I keep old and deprecated versions of PostgreSQL in this repository instead of removing them, because they are sometimes useful to have handy, and also for curiosity. Mainly because I can't test that anymore, YMMV. I have also dropped supported for legacy macOS concerns, such as 32-bit Intel and PowerPC and really old macOS releases. These formulae enable all configure options that macOS can support, but also remove a number of Homebrew-level build options, to reduce complexity. The standard postgresql formula in Homebrew is missing a number of build options and also has a number of build options that I find useless. This is not a problem, however, because the versioned packages provide the same functionality. But there will be a conflict if you do brew link -f or install postgresql-common, so in those cases you have to uninstall the main postgresql package first. The versioned formulae can be installed alongside the main postgresql formula in Homebrew.
Brew install postgresql full#
So far, Homebrew had inconsistent support for that and did not provide the full range of supported major versions. Since PostgreSQL major releases have incompatible data directories and other occasional incompatibilities, it is useful for many developers to keep several major versions installed in parallel for development, testing, and production. Since there might be name overlaps with core Homebrew formulae, you should use fully qualified formula names like brew install petere/postgresql/postgresql-common. To install something, first brew tap petere/postgresql and then brew install. This is similar to what you can do on certain Linux distributions, for example Debian. Will keep trying.These formulae allow installing multiple versions of PostgreSQL in parallel. It seems to be working now, but unfortunately I have the problem that my database is already on 2.4 and there seems to be no downgrade path. However, I had to use ln -s instead of cp -a.
Brew install postgresql how to#
How to install PostGIS with older PostgreSQL versions, i.e. Therefore my question can be answered in two ways.
That means I can't back nor forth: I cannot figure out how to get PostGIS working with and I cannot pg_upgrade to the new version of PostgreSQL (10.1). Ok, so "time to jump to PostgreSQL 10.1", I though, but pg_upgrade now gets stuck with the errorĮRROR: could not access file "$libdir/postgis-2.3": No such file or directory From time to time I do brew cleanup and somehow I am now left with a broken PostGIS database. Again, one can pin PostGIS, yet Homebrew/core does not offer previous versions.
So far so good, but the problem is that PostGIS also keeps updating and eventually will be incompatible with pinned or Homebrew/core versions of PostgreSQL. Whenever a major release of PostgreSQL appears, homebrew will happily install it right away, unless one pins a certain version or installs a specific version from Homebrew/core. As there are two ways to solve this question, I asked for another approach here.
