PGPASSFILE behaves the same as the passfile connection parameter.
passfile
Specifies the name of the file used to store passwords (see Section 33.15). Defaults to ~/.pgpass, or %APPDATA%\postgresql\pgpass.conf on Microsoft Windows. (No error is reported if this file does not exist.)

PGPASSFILE specifies the name of the password file to use for lookups. If not set, it defaults to ~/.pgpass (see Section 31.15).

verifying it doesn't access the default:
pryzbyj(at)pryzbyj:~$ echo quit |PGPASSFILE=/nonextant strace psql 2>&1 |grep -E 'nonex|pgpass'
stat("/nonextant", 0x7fffbd13c9f0) = -1 ENOENT (No such file or directory)
pryzbyj(at)pryzbyj:~$
