You could also use homebrew to install libpq.
brew install libpq
On Mac M1
arch -arm64 brew install libpq
This would give you
pg_dump and a whole bunch of other client utilities without installing Postgres.
Unfortunately since it provides some of the same utilities as are included in the full
postgresql package, brew installs it “keg-only” which means it isn’t in the PATH by default. Homebrew will spit out some information on how to add it to your PATH after installation. In my case it was this:
echo 'export PATH="/opt/homebrew/Cellar/libpq/13.3/bin:$PATH"' >> ~/.zshrc
Alternatively, you can create symlinks for the utilities you need. E.g.:
ln -s /opt/homebrew/Cellar/libpq/13.3/bin/psql /usr/local/bin/psql
Note: used installed version instead of 13.3.
Alternatively, you could instruct homebrew to “link all of its binaries to the PATH anyway”
brew link --force libpq
but then you’d be unable to install the
postgresql package later.
