PostgreSQL version: Unsupported/Unknown
Operating system:   macOS
Description:        

When I went to https://www.postgresql.org/download/macosx/, there is a link
in the sentence:

> A list of PostgreSQL packages can be found using the Braumeister search
tool.

And the link is https://formulae.brew.sh/formula/postgresql.

However, the link is broken. Please consider changing the link. Thanks.
