Postgresql linking requirement unclear #1380

Describe the bug

I've been using the osgeo-gdal formula for a while now. osgeo-gdal depends on osgeo-postgresql. However as my usecase does not involve postgres integration I was already using the postgresql from homebrew-core and didn't want to change that I instead installed osgeo-postgresql@11 keg-only. Everything was fine until I upgraded to 3.1.0 version, failed and realized now all osgeo-postgresql formulas, including @10 and @11 require linking and my setup of linked homebrew-core/postgresql + keg-only osgeo-postgresql@11 doesn't work anymore. May I ask what prompted the change and is it possible to revert it so that keg-only installation of osgeo-postgresql@10/@11 is enough because if I'm not wrong originally that was the intended behavior as seen in the caveat section of these formulas

Hi @kiendang. I'm not sure what "I upgraded and failed" mean in this case, do you mean the upgrade process failed or some function of GDAL did? As far as I know, it's done this way to ensure compatibility between PostgreSQL and the GDAL driver. However, you could unlinking it after the GDAL installation and link again your desired version, whether core or osgeo.

Yes that's what I did. But considering 1. the package works fine without linking osgeo-postgres and 2. homebrew-core/postgresql is one of the most commonly installed formulae is it better to not require linking? Or at least change the caveat message which implies linking is not required

osgeo-postgresql formulas are also thought as companions to osgeo-postgis formulas or osgeo-grass, so it'd make sense to link all of them and keep them working together as the standard.

There is an open debate though whether we should use core formulas again instead. At this moment the main advantages are finer control to upgrades and python extensions in osgeo formulas.

I agree caveats message could be adjust, perhaps with this explanation https://github.com/OSGeo/homebrew-osgeo4mac/issues/1380#issuecomment-633206747. Would you suggest something different?
