A command line argument and the parameter it links to are two separate
things.

Also, the libpq environments variables's documentation says PGDATABASE

Which the linked portion then says:

"In certain contexts, the value is checked for extended formats;"

Which implies that PGDATABASE envvar interpretation is not one of those
places where the extended URI connection string format can be passed;
instead the environment variables covering the different parts need to be
used. Using them works one-to-one with the plain meaning of the parameters
they link to.

Probably the docs could use a note to that effect.
