psql: command not found Mac

From the Postgres documentation page:

sudo mkdir -p /etc/paths.d && echo /Applications/ | sudo tee /etc/paths.d/postgresapp

restart your terminal and you will have it in your path.

You have got the PATH slightly wrong. You need the PATH to "the containing directory", not the actual executable itself.

Your PATH should be set like this:

export PATH=/Library/PostgreSQL/9.5/bin:$PATH

without the extra sql part in it. Also, you must remove the spaces around the equals sign.
