The following bug has been logged on the website:

Bug reference: 15499
Logged by: Yonatan Romero
Email address: yromero@onapsis.com
PostgreSQL version: Unsupported/Unknown
Operating system: Ubuntu 14.04 LTS
Description:

pg_dump's docs says this command can use connection string on --dbname
argument[1]https://www.postgresql.org/docs/9.3/app-pgrestore.html.

Also, the libpq environments variables's documentation says PGDATABASE
behaves the same as the dbname connection parameter[2]https://www.postgresql.org/docs/9.3/libpq-envars.html.

I try to pass connection string on PGDATABASE environment variable, but it
does work.

yromero@onapsis:~$ env
PGDATABASE="postgresql://onapsis:secret@localhost/onapsis" pg_dump
pg_dump: [archiver (db)] connection to database
"postgresql://onapsis:secret@localhost/onapsis" failed: FATAL: role
"yromero" does not exist

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

Also, the libpq environments variables's documentation says PGDATABASE

behaves the same as the dbname connection parameter[2].

Which the linked portion then says:

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

I try to pass connection string on PGDATABASE environment variable, but it

does [not] work.

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.
