Please find attached a patch to add PGInstaller to the Downloads section of postgresql.org.
PGInstaller offers an easy way to install PostgreSQL. We have found this to be crucial to our customers who are used to GUI-based, click-n-point installers on Windows and at times on macOS. PGInstaller has evolved from 2UDA, a package that 2ndQuadrant has been working on for more than 3 years.
2ndQuadrant is committed to developing and actively maintaining PGInstaller for PostgreSQL versions 9.5 and above. We have been releasing, and will continue to release, updates in sync with the PostgreSQL community, most recently announcing the minor release on 9-Aug. PGInstaller has also kept up with the Beta releases for PostgreSQL 11.
The first issue that I can see (or more correctly, not see), is the source code. All packages on these pages need to be 100% Open Source, including the code required to build the packages themselves (but not necessarily the tools/compilers of course). Where can the code be found?
Secondly, it looks like your ordering is not quite as it should be on some pages. We list native packages first, followed by non-native, then third party packaging systems, with new additions at the end of the appropriate section to limit confusion for users (particularly those who pick the first item then later try to upgrade it).
E.g. on the Ubuntu page, it should be:
PG APT Repo
BigSQL DEB Packages
EDB Installers
2ndQ Installers
On the Mac page:
EDB Installers
BigSQL Installers
Postgres.app
2ndQ Installers
Similarly for other pages.
Finally; "PGInstaller" is the name used by the original Windows packaging that Magnus and I used to maintain (http://pgfoundry.org/projects/pginstaller/). I for one would appreciate it if you didn't use that name, but came up with something original.
